It seems like this should be easy and I've spent hours trying to find this answer online but haven't had any luck.
I can open the CLion folder path in Visual Studio, but that option doesn't give me the usual options to build and start the project. To do that, I need to open CLion as a Project/Solution, but I can't seem to do this.
My professor requires that my C++ code be executable in Visual Studio, but I prefer CLion. So I've done all my work in CLion and want to test that it runs in Visual Studio. How can I import my CLion project?
Thanks!
The link provided describes Visual Studio's CMake integration, which (similar to CLion) will install a version of CMake that Visual Studio will use. These instructions are pretty thorough and should provide everything needed to get your CMake project working in Visual Studio.
Now, you probably have two versions of CMake installed on your machine, one that came with CLion and one that came with Visual Studio. I would recommend installing the latest version of CMake on your machine separately, and configuring both Visual Studio and CLion to use that version instead. However, this is probably getting outside the scope of your immediate problem.
As you follow the Microsoft's instructions for "CMake projects in Visual Studio", you mentioned receiving the error:
1> [CMake] CMake Error at C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/Common7/IDE/CommonExtensions/Microsoft/CMake/CMake/share/cmake-3.17/Modules/CMakeDetermineSystem.cmake:173 (file):
1> [CMake] file failed to open for writing (No such file or directory):
This looks like a permissions issue, specifically while running CMake within Visual Studio, so be sure you have read/write access to all the files in your project, and the CMake packages in your Visual Studio installation. Hopefully, this doesn't require you re-install Visual Studio in another location on your machine, or run Visual Studio with elevated privileges, but perhaps that is necessary.
If you decide to install CMake separately, the instructions would be the following:
Install the latest CMake on your machine (somewhere you have adequate permissions), and ensure it is available in your Path environment variable. You can verify this by running cmake -version from the command line to see it is the version you just installed.
Using Windows command prompt, navigate to your CMake project directory (containing the top-level CMakeLists.txt file), and run the following:
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -A x64 ..
You may run -A Win32 with the cmake command instead if your project is a 32-bit build.
Open the .sln Visual Studio Solution file that was generated in the build directory. Once, the Solution is loaded in Visual Studio, you can build the project (CTRL + SHIFT + B).

I'm using Visual Studio to open a CMake C++ project. When I set it to x64-Debug mode at the top and compile, it works fine. However, when I change it to x64-Release, it suddenly tells me:
CMake Error at CMakeLists.txt:5 (project):
Generator
Visual Studio 16 2019
could not find any instance of Visual Studio.
I'm literally using Visual Studio, why does CMake not find it anymore when building in release mode? I know that this code base compiled perfectly fine before and I didn't make any changes to it since then. Also, I tried to repair/reinstall Visual Studio but the issue persists. Can I verify some environment variables or whatever CMake checks?
When running CMake from CMD directly to generate a Visual Studio solution (cmake -G "Visual Studio 16 2019"), I get the same error as above. Running from x64 Native Tools Command Prompt for VS 2022" or Developer Command Prompt for VS 2022 does not help either.
Desktop development with C++ and C++ CMake tools for Windows are both installed.
>cmake --version
cmake version 3.24.2
CMake suite maintained and supported by Kitware (kitware.com/cmake).
It turns out that deleting all Visual Studio generated files/folders and setting up a new x64-Release configuration solved the problem.
I am using cmake to generate visual studio project and build it. I am using the following command on my local machine on which visual studio is installed and works fine:
cmake.exe -G "Visual Studio 15 2017 Win64" $(CMAKE_ARGS)
However, I cannot install visual studio on my build server and therefore the above command will fail. During the build I can copy as many files as I want on my build server but I just cannot install anything during the build. Is there anyway to do this without installing VS?
I came across the following cmake argument;
CMAKE_GENERATOR_INSTANCE
which seems to be pointing to the instance of the generator. I was wondering if I could copy the necessary files to my build machine and have this variable point to it in order to generate? Is this how it works? if not, is there a way to generate VS projects using cmake without installing visual studio on the build machine?
I'm trying make a Visual Studio solution with CMake to compile the latest version of aseprite and CMake keeps giving me the:
No CMAKE_C_COMPILER could be found.
No CMAKE_CXX_COMPILER could be found.
I've already downloaded GCC, and I'm using Visual Studio 2015.
I'm following this tutorial:
https://github.com/aseprite/aseprite/blob/master/INSTALL.md
For Ubuntu, please install the below things:
sudo apt-get update && sudo apt-get install build-essential
Those error messages
CMake Error at ... (project):
No CMAKE_C_COMPILER could be found.
-- Configuring incomplete, errors occurred!
See also ".../CMakeFiles/CMakeOutput.log".
See also ".../CMakeFiles/CMakeError.log".
or
CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.
Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
...
-- Configuring incomplete, errors occurred!
just mean that CMake was unable to find your C/CXX compiler to compile a simple test program (one of the first things CMake tries while detecting your build environment).
The steps to find your problem are dependent on the build environment you want to generate. The following tutorials are a collection of answers here on Stack Overflow and some of my own experiences with CMake on Microsoft Windows 7/8/10 and Ubuntu 14.04.
Preconditions
You have installed the compiler/IDE and it was able to once compile any other program (directly without CMake)
You e.g. may have the IDE, but may not have installed the compiler or supporting framework itself like described in Problems generating solution for VS 2017 with CMake or How do I tell CMake to use Clang on Windows?
You have the latest CMake version
You have access rights on the drive you want CMake to generate your build environment
You have a clean build directory (because CMake does cache things from the last try) e.g. as sub-directory of your source tree
Windows cmd.exe
> rmdir /s /q VS2015
> mkdir VS2015
> cd VS2015
Bash shell
$ rm -rf MSYS
$ mkdir MSYS
$ cd MSYS
and make sure your command shell points to your newly created binary output directory.
General things you can/should try
Is CMake able find and run with any/your default compiler? Run without giving a generator
> cmake ..
-- Building for: Visual Studio 14 2015
...
Perfect if it correctly determined the generator to use - like here Visual Studio 14 2015
What was it that actually failed?
In the previous build output directory look at CMakeFiles\CMakeError.log for any error message that make sense to you or try to open/compile the test project generated at CMakeFiles\[Version]\CompilerIdC|CompilerIdCXX directly from the command line (as found in the error log).
CMake can't find Visual Studio
Try to select the correct generator version:
> cmake --help
> cmake -G "Visual Studio 14 2015" ..
If that doesn't help, try to set the Visual Studio environment variables first (the path could vary):
> "c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat"
> cmake ..
or use the Developer Command Prompt for VS2015 short-cut in your Windows Start Menu under All Programs/Visual Studio 2015/Visual Studio Tools (thanks at #Antwane for the hint).
Background: CMake does support all Visual Studio releases and flavors (Express, Community, Professional, Premium, Test, Team, Enterprise, Ultimate, etc.). To determine the location of the compiler it uses a combination of searching the registry (e.g. at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[Version];InstallDir), system environment variables and - if none of the others did come up with something - plainly try to call the compiler.
CMake can't find GCC (MinGW/MSys)
You start the MSys bash shell with msys.bat and just try to directly call gcc
$ gcc
gcc.exe: fatal error: no input files
compilation terminated.
Here it did find gcc and is complaining that I didn't gave it any parameters to work with.
So the following should work:
$ cmake -G "MSYS Makefiles" ..
-- The CXX compiler identification is GNU 4.8.1
...
$ make
If GCC was not found call export PATH=... to add your compilers path (see How to set PATH environment variable in CMake script?) and try again.
If it's still not working, try to set the CXX compiler path directly by exporting it (path may vary)
$ export CC=/c/MinGW/bin/gcc.exe
$ export CXX=/c/MinGW/bin/g++.exe
$ cmake -G "MinGW Makefiles" ..
-- The CXX compiler identification is GNU 4.8.1
...
$ mingw32-make
For more details see How to specify new GCC path for CMake
Note: When using the "MinGW Makefiles" generator you have to use the mingw32-make program distributed with MinGW
Still not working? That's weird. Please make sure that the compiler is there and it has executable rights (see also preconditions chapter above).
Otherwise the last resort of CMake is to not try any compiler search itself and set CMake's internal variables directly by
$ cmake -DCMAKE_C_COMPILER=/c/MinGW/bin/gcc.exe -DCMAKE_CXX_COMPILER=/c/MinGW/bin/g++.exe ..
For more details see Cmake doesn't honour -D CMAKE_CXX_COMPILER=g++ and Cmake error setting compiler
Alternatively those variables can also be set via cmake-gui.exe on Windows. See Cmake cannot find compiler
Background: Much the same as with Visual Studio. CMake supports all sorts of GCC flavors. It searches the environment variables (CC, CXX, etc.) or simply tries to call the compiler. In addition it will detect any prefixes (when cross-compiling) and tries to add it to all binutils of the GNU compiler toolchain (ar, ranlib, strip, ld, nm, objdump, and objcopy).
This happened to me after I installed Visual Studio 15 2017.
The C++ compiler for Visual Studio 14 2015 was not the problem. It seemed to be a problem with the Windows 10 SDK.
Adding the Windows 10 SDKs to Visual Studio 14 2015 solved the problem for me.
See attached screenshot.
This works for me in Ubuntu 17.10 (Artful Aardvark):
apt-get update
apt-get install build-essential
I also experienced this error when working with CMake:
No CMAKE_C_COMPILER could be found.
No CMAKE_CXX_COMPILER could be found.
The 'warning' box in the MSDN library article Visual C++ in Visual Studio 2015 gave me the help that I needed.
Visual Studio 2015 doesn't come with C++ installed by default. So, creating a new C++ project will prompt you to download the necessary C++ components.
I ran into this issue while building libgit2-0.23.4. For me the problem was that C++ compiler & related packages were not installed with VS2015, therefore "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" file was missing and Cmake wasn't able to find the compiler.
I tried manually creating a C++ project in the Visual Studio 2015 GUI (C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe)
and while creating the project, I got a prompt to download the C++ & related packages.
After downloading required packages, I could see vcvarsall.bat & Cmake was able to find the compiler & executed successfully with following log:

I had the same errors with CMake. In my case, I have used the wrong Visual Studio version in the initial CMake dialog where we have to select the Visual Studio compiler.
Then I changed it to "Visual Studio 11 2012" and things worked. (I have Visual Studio Ultimate 2012 version on my PC). In general, try to input an older version of Visual Studio version in the initial CMake configuration dialog.
For me, this problem went away on Windows when I moved my project to a shallower parent directory, i.e. to:
C:\Users\spenc\Desktop\MyProjectDirectory
instead of
C:\Users\spenc\Desktop\...\MyProjectDirectory.
I think the source of the problem was that MSBuild has a file path length restriction to 260 characters. This causes the basic compiler test CMake performs to build a project called CompilerIdCXX.vcxproj to fail with the error:
C1083: Cannot open source file: 'CMakeCXXCompilerId.cpp'
because the length of the file's path e.g.
C:\Users\spenc\Desktop\...\MyProjectDirectory\build\CMakeFiles\...\CMakeCXXCompilerId.cpp
exceeds the MAX_PATH restriction.
CMake then concludes there is no CXX compiler.
Make sure you have selected the correct version of Visual Studio. This is trickier than it seems because Visual Studio 2015 is actually Visual Studio 14, and similarly Visual Studio 2012 is Visual Studio 11. I had incorrectly selected Visual Studio 15 which is actually Visual Studio 2017, when I had 2015 installed.
After trying out all of the solutions with no luck, I just provided those missing parameter by cmake -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ ...
Make sure you have installed Windows SDK when you were installing Visual Studio. To add windows SDK you can go to Visual Studio Installer and hit "Modify" and then tick the checkbox of Windows SDK and install it.
None of the solutions here solves my problem - only when I install Windows Update for universal C runtime.
Now CMake is working and no more link hangs from Visual Studio.
Update for Universal C Runtime in Windows
You can also make sure you are the sudo user and you have READ/WRITE access on the directory you are working. I had a similar problem on OS X, and I got it fixed just by entering in sudo mode.
Just in case it helps any one like me in future:
I have had this issue for 24 hours now, on 3 different 64-bit machines(Win7 , Windows 8.1 VM and WIn 8.1 laptop) - whilst trying to build WebKit with VS 2017.
The simple issue here is that the VC++ compiler (i.e cl.exe and it's dependent DLLs) is not visible to CMake. Simple. By making the VC++ folders containing those binaries visible to CMake and your working command prompt(if you're running Cmake from a command prompt), voila! (In addition to key points raised by others , above)
Anyway, after all kinds of fixes - as posted on these many forums- I discovered that it was SIMPLY a matter of ensuring that the PATH variable's contents are not cluttered with multiple Visual Studio BIN paths etc; and instead, points to :
a) the location of your compiler (i.e. cl.exe for your preferred version of Visual Studio ), which in my case(targeting 64-bit platform, and developing on a 64-bit host) is:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.15.26726\bin\Hostx64\x64
b) and in addition, the folder containing a dependent DLL called (which cl.exe is dependent on):
api-ms-win-crt-runtime-l1-1-0.dll - which on my machine is:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\Remote Debugger\x64
These two directories being added to a simplified and CUSTOM System Path variable(working under a Admin priviledged commmand prompt), eliminated my "No CMAKE_C_COMPILER could be found" and "No CMAKE_CXX_COMPILER could be found." errors.
Hope it helps someone.
I get exactly the reported error if ccache is enabled, when using CMake's Xcode generator. Disabling ccache fixed the problem for me. Below I present a fix/check that works for MacOS, but should work similarly on other platforms.
Apparently, it is possible to use CMake's Xcode generator (and others) also in combination with ccache, as is described here. But I never tried it out myself.
# 1) To check if ccache is enabled:
echo $CC
echo $CXX
# This prints something like the following:
# ccache clang -Qunused-arguments -fcolor-diagnostics.
# CC or CXX are typically set in the `.bashrc` or `.zshrc` file.
# 2) To disable ccache, use the following:
CC=clang
CXX=clang++
# 3) Then regenerate the cmake project
cmake -G Xcode <path/to/CMakeLists.txt>
I know this question is about visual studio 2015. I faced this issue with visual studio 2017. When searched on google I landed to this page. After looking at first 2,3 answers I realized this is the problem with vc++ installation. Installing the workload "Desktop development with c++" resolved the issue.
I updated Visual Studio 2015 update 2 to Visual Studio 2015 update 3, and it solved my problem.
I had the same issue with cmake-gui (No CMAKE_CXX_COMPILER could be found.), while running CMake from the command line worked fine. After manually adding the entries
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin
to the PATH environment variable it worked for me.
For me it worked to use the Developer Command Prompt that comes with Visual Studio and then just cd to your/jcef/dir and run cmake -G "Visual Studio 14 Win64" ..
I had the same problem.
I was trying to install dlib on my machine and it gave me this error.
The tutorial mentioned in the question leads to downloading visual studio 2017. I solved this by uninstalling VS 2017 and installing VS 2015
One can install VS 2015 via this stackoverflow thread :
How to download Visual Studio Community Edition 2015 (not 2017)
Look in the Cmakelists.txt if you find ARM you need to install C++ for ARM
It's these packages:
C++ Universal Windows Platform for ARM64 "Not Required"
Visual C++ Compilers and libraries for ARM "Not Required"
Visual C++ Compilers and libraries for ARM64 "Very Likely Required"
Required for finding Threads on ARM
enable_language(C)
enable_language(CXX)
Then the problems
No CMAKE_C_COMPILER could be found.
No CMAKE_CXX_COMPILER could be found.
Might disappear unless you specify c compiler like clang, and maybe installing clang will work in other favour.
You can with optional remove in cmakelists.txt both with # before enable_language if you are not compiling for ARM.
On M1 Mac, add the following config to fix it for me
-DCMAKE_C_COMPILER="${OTHER_CXX_FLAG}" -DCMAKE_C_COMPILER="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang" -DCMAKE_CXX_COMPILER="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++"
The config result is:
cmake ../build -DCMAKE_C_COMPILER="${OTHER_CXX_FLAG}" -DCMAKE_C_COMPILER="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang" -DCMAKE_CXX_COMPILER="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++" -DCMAKE_SYSTEM_NAME=Darwin -DCMAKE_TARGET_SYSTEM=mac -GXcode
After installing Visual Studio 2015 and running CMake on a previous project, CMake errors stating that it could not find the C compiler.
The C compiler identification is unknown
The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:4 (PROJECT):
No CMAKE_C_COMPILER could be found.
CMake Error at CMakeLists.txt:4 (PROJECT):
No CMAKE_CXX_COMPILER could be found.
I went searching for cl.exe in the Visual Studio folder,C:\Program Files\Microsoft Visual Studio 14.0, and could not find it.
How do I set up CMake to work on Windows with Visual Studio 2015?
I have found the solution. While the Visual Studio IDE installed successfully it did not install any build tools and therefore did not install the C++ compiler.
By attempting to manually create a C++ project in the Visual Studio 2015 GUI I was able to prompt it to download the C++ packages. CMake was then able to find the compiler without any difficulty.
Here is the solution that worked for me:
Open Visual Studio command prompt tool (as an administrator). On windows 10 it might be called 'Developer command prompt'.
Navigate to where you have the CMake executable
Run Cmake.exe
Proceed as usual to select build and source folder
Select the appropriate Visual Studio compiler and hit the configure button
Hopefully it should run without problems.
I looked in CMakeError.log file and found an error about cannot run 'rc.exe'
I searched and found this answer to copy RC.Exe and RcDll.Dll from the Microsoft SDKs bin to the VC bin, and then CMake worked.
Edit: The top answer to another question suggests that it's a PATH issue, so it could be enough to ensure the Microsoft SDK bin is in your PATH.
Those stumbling with this on Visual Studio 2017: there is a feature related to CMake that needs to be selected and installed together with the relevant compiler toolsets. See the screenshot below.
Make sure you are using the correct version of Visual Studio in the generator. I had incorrectly selected Visual Studio 15 when Visual Studio 14 installed.
If none of the above solutions worked, then stop and do a sanity check.
I got burned using the wrong -G <config> string and it gave me this misleading error.
First, run from the VS Command Prompt not the regular command prompt. You can find it in
Start Menu -> Visual Studio 2015 -> MSBuild Command Prompt for VS2015 This sets up all the correct paths to VS tools, etc.
Now see what generators are available from cmake...
cmake -help
...<snip>...
The following generators are available on this platform:
Visual Studio 15 [arch] = Generates Visual Studio 15 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 14 2015 [arch] = Generates Visual Studio 2015 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 12 2013 [arch] = Generates Visual Studio 2013 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 11 2012 [arch] = Generates Visual Studio 2012 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 10 2010 [arch] = Generates Visual Studio 2010 project files.
Optional [arch] can be "Win64" or "IA64".
...
Then chose the appropriate string with the [arch] added.
mkdir _build
cd _build
cmake .. -G "Visual Studio 15 Win64"
Running cmake in a subdirectory makes it easier to do a 'clean' since you can just delete everything in that directory.
I upgraded to Visual Studio 15 but wasn't paying attention and was trying to generate for 2012.
For me, I checked the CMakeError.log file and found:
[...] error MSB8036: The Windows SDK version 8.1 was not found. Install the required version of Windows SDK or change the SDK version in the project property pages or by right-clicking the solution and selecting "Retarget solution".
This is despite using Visual Studio 2017 on Windows 7. So it appears that CMake is trying to build its detection project with the Windows 8.1 SDK.
I used the Visual Studio installer to add that component and now CMake is happy as a clam.
Menu → Visual Studio 2015 → MSBuild Command Prompt for Visual Studio 2015. Then CMake can find cl.exe.
set PATH="c:\Program Files (x86)\Windows Kits\10\bin\10.0.16299.0\x64\";%PATH%
Change the upper path to where your Windows SDK is installed.
CMake can find rc.exe.
cd to the path of CMakeLists.txt and do:
md .build
cd .build
cmake .. -G "Visual Studio 14 2015 Win64" -DCMAKE_BUILD_TYPE=Release
cmake --build .
The param after -G should be fetched by CMake. Use --help; you may or may not have the generator.
I ran into the same issue and fixed it by relaunching the Visual Studio Install and checking the following option:
Windows and Web Development / Universal Windows App Development Tools / Windows 10 SDK
It contains the standard C++ headers used in most applications and therefore it is often necessary to install it as well.
I had this issue under Windows 10 when using Visual Studio 2015 Professional, while Visual Studio 2015 Express worked! Under Windows 7, both Visual Studio versions used to work.
New projects created from the Visual Studio 2015 Professional IDE successfully compile, but CMake would fail to find the compiler reporting:
The C compiler identification is unknown
The CXX compiler identification is unknown
I upgraded CMake from 3.4.1 to 3.11.4, and now the problem is gone.
If you are on Visual Studio 2017 you need at least CMake 3.8!
I had a similar problem with the Visual Studio 2017 project generated through CMake. Some of the packages were missing while installing Visual Studio in Desktop development with C++. See snapshot:
Visual Studio 2017 Packages:
Also, upgrade CMake to the latest version.
Checking CMakeErrors.log in CMakeFiles returned:
C:\Program Files
(x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Platforms\x64\PlatformToolsets\v140_xp\Toolset.targets(36,5): warning MSB8003: Could not find WindowsSdkDir_71A variable from the
registry. TargetFrameworkVersion or PlatformToolset may be set to an
invalid version number.
The error means that the build tools for XP (v140_xp) are not installed. To fix it I installed the proper feature in Visual Studio 2019 installer under Individual Components tab:
I was running old cmake version (i.e. 3.8) and I'm using visual studio 16 - 2019. After updating my cmake version, it did detect the compiler.
In my case there was an environment variable set which was the reason for this error.
The problem was solved after deleting cxx_flags from the environment variables.
I got this problem with CMake 3.12.1, after an update of Visual Studio 2017. I simply re-ran CMake and it worked.
In my case I could see in the CMakeError.log that CMake could not find the Windows SDK (MSB8003: Could not find WindowsSDKDir variable from the registry).
The version can be specified on the commandline on the first CMake run using:
-DCMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION=
I got further after setting that, but I hit more issues later (so I assume my environment is messed up somehow), but maybe it will help someone with this issue.
A couple of tips:
Try to set the path manually by checking 'advanced' and modifying CMAKE_LINKER and CMAKE_MAKE_PROGRAM
Delete the cache - in the CMake with GUI go to:
File → Delete Cache.
My problem was a combination of previously stated: I have set the compiler version to 15 instead of 14 and when corrected, I had to delete the cache.
I also started the Visual Studio command prompt as an administrator and from there I ran the cmake-gui.exe
Then everything worked as it was supposed to.
In my case the issue was that the parent project, which is including googletest via
add_subdirectory(gtest_dir)
was defined as
PROJECT( projname CXX )
Somehow, CMake does not recognize
PROJECT(sub_project_name CXX C)
since the C compiler is not set in the parent.
I solved the issue by using
PROJECT( projname CXX C)
in my main CMakeLists.txt file.
This might be another solution for those with the latest Windows 10 creator version:
Stack Overflow post Fatal error LNK1104: cannot open file 'gdi32.lib'
None of the previous solutions worked for me. However I noticed that although I installed Visual Studio version 15 (not to be confused with Visual Studio 2015) the directory created on my computer was for Visual Studio 14.
When I specified Visual Studio 14 when I pressed the configuration button it worked.
i found this sollution at stackoverflow and i work for me although not working other sollutions
if you have a windows 10 OS, doing the following steps will fix the problem:
1) go to C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Bin
2) then copy RC.exe and RcDll from this file
3) go to C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin and paste the two files you have copied into it.
thats all i hope it is helpful...
Look in the Cmakelists.txt if you find ARM you need to install C++ for ARM and as well vcvarsall.bat use for ARM bin folder.
It's these packages:
C++ Universal Windows Platform for ARM64 "Not Required"
Visual C++ Compilers and libraries for ARM "Not Required"
Visual C++ Compilers and libraries for ARM64 "Very Likely Required"
Required for finding Threads on ARM
enable_language(C)
enable_language(CXX)
Then the problems might disappear:
No CMAKE_C_COMPILER could be found.
No CMAKE_CXX_COMPILER could be found.
If above does not resolve your problem?
Optionally you can remove the options C and CXX in cmakelists.txt by setting # infront of where the enable_language(C) is. And avoid Android ARM processor compilation.

I had a related problem: the Visual C++ generators were not even on the list when running cmake --help.
I ran where cmake in console and found that cygwin also provides its own cmake.exe file, which was being used. Changing the order of directories in PATH fixed the problem.
I had this issue with CMake GUI and the VS 21019 Community Edition. I think I may have installed CMake before Visual Studio - certainly after I updated CMake 3.15.2 to 3.15.3 the problem went away.
Check name folder too long or not.
This question is old, but none of the solutions here were working for me. I'm using Visual Studio 2019, and in my case, C++ compilation was working but just broke one day.
However, I noticed that there was an update ready to be installed in the Visual Studio Installer.
After installing that update, rebooting my computer, and relaunching Visual Studio, all of the C++ CMake problems disappeared. I'm not quite sure why this fixed it, and I can only speculate, but I can only assume that one of two things occurred. Either installing that update fixed a broken installation, or the update was quietly downloaded and prepared in the background, breaking things in the process.
I met the same issue in VSCode Cmake extension, i solve it by check following two options:
In the end, click [Scan for kits]
cmake --no-warn-unused-cli -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug "-DCMAKE_C_COMPILER:FILEPATH=C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin\gcc.exe" "-DCMAKE_CXX_COMPILER:FILEPATH=C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin\g++.exe" -Hc:/code -Bc:/code/build -G "MinGW Makefiles"
I'm trying to automate the building process for a certain open source project. It will do an update on the SVN directory, use CMake to get a .sln file, and build that. I can successfully do this manually, and do svn and cmake from a batch script, but Now I need to build the solution.
A quick google search revealed:
devenv /build release /project <projname> <solutionfile>.sln
However, that uses the latest version of visual studio (Visual Studio Professional 2011), while the .sln file generated is for Visual C++ Express 2008. I have both versions installed on my computer. Is there a devenv I can use for Visual C++ Express 2008? Or is there a commandline argument to specify which version to use?
UPDATE
I tried using msbuild, but that didn't seem to like building .vcproj files directly, and I didn't want to build ALL the project files by having it build the .sln file. I ended up using this:
"C:\Program Files\Microsoft Visual Studio 9.0\VC\vcpackages\vcbuild.exe" <myproj>.vcproj "Release|Win32"
I think you are using the wrong tool to build this. Rather than trying to drive the IDE from the command line you should simply use msbuild.
msbuild.exe projectname.proj /property:Configuration=Release
In order to set your environment up for the specific version of MSVC you need to call the vcvar.bat file from that specific version. This will set up the necessary environment variables needed by the build tools.
For Visual Studio Express 2008 the IDE is called VCExpress.exe. Also you should probably specify the full path of the program when you have two versions installed:
C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\VCExpress.exe /build release /project <projname> <solutionfile>.sln
