CMake error in FindTerminfo with clang-15 on MacOS - c++

I'm using llvm in my project and find it with cmake's find_package(LLVM REQUIRED CONFIG).
Configuration fails with message:
[cmake] CMake Error at /Applications/CMake.app/Contents/share/cmake-3.23/Modules/Internal/CheckSourceCompiles.cmake:44 (message):
[cmake] check_source_compiles: C: needs to be enabled before use.

[cmake]
[cmake] -- Could NOT find Terminfo (missing: Terminfo_LINKABLE)

How to fix it?

It's actually a well-known issue in clang-14 and greater.
Temporary solution is to use C language in your project.
project(test LANGUAGES C CXX) # instead of project(test LANGUAGES CXX)

How to link "ShaderWriter" with vcpkg and cmake?

I want to link the library ShaderWriter with CMake and vcpkg.
However, when I have the following two lines in my CMakeLists.txt:
find_package(ShaderWriter CONFIG REQUIRED)
target_link_libraries(Game PRIVATE sdw::ShaderAST sdw::CompilerGlsl sdw::CompilerHlsl sdw::ShaderWriter)
I receive the following cmake error:
[CMake] CMake Error at D:/Dokumente/Repositories/vcpkg/scripts/buildsystems/vcpkg.cmake:534 (_add_executable):
[CMake] Target "Game" links to target "sdw::CompilerGlsl" but the target was not
[CMake] found. Perhaps a find_package() call is missing for an IMPORTED target, or
[CMake] an ALIAS target is missing?

What am I missing? After installing ShaderWriter, It suggests only the two lines I inserted.
The usage suggested by vcpkg is misleading.
In share/shaderwriter there are two *Config.cmake files:
ShaderWriterConfig.cmake and SdwCompilersConfig.cmake. The targets mentioned in your error output come from SdwCompilersConfig.cmake hence you should add both find_package(ShaderWriter CONFIG REQUIRED) and find_package(SdwCompilers CONFIG REQUIRED) calls.

How to fix warning "Found OpenCV Windows Pack but it has no binaries compatible with your configuration"?

I am trying to use OpenCV in VS Code.
Here's what I've done:
Installed OpenCV for windows.
Added "C:\opencv\build\x64\vc15\bin","C:\opencv\build\x64\vc15\lib" PATH environment variable.
Here's my CMakeLists.txt file.
cmake_minimum_required(VERSION 3.0.0)
project(opencvtest VERSION 0.1.0)
include(CTest)
enable_testing()
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable(opencvtest main.cpp)
target_link_libraries( opencvtest ${OpenCV_LIBS} )
set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)
But the file throws the following error:

I am trying to run a C++ file in VS Code that includes <opencv2/opencv.hpp>.
As the error suggests, CMake found your OpenCV installation, but it is not compatible. What is it not compatible with? Your compiler. The OpenCV installation is built with MSVC 15 (it also includes a 14 build). You have asked CMake to use MinGW as your compiler. Libraries need to have been built with the same (well, with some leeway) compiler for everything to work.
You have two options:
Build OpenCV yourself with MinGW, or try a third-party MinGW binary distribution of OpenCV. Web searches for "opencv mingw" turn up some
possibilities.
Use the MSVC compiler for your project. Microsoft offers some free versions of its tools. Just be sure to install the optional older toolsets so that you have access to the VC 15 tools to match OpenCV.

Use CppADCodeGen with CMake FetchContent or ExternalProject

I am not good with CMake, and I cannot find good explanations about how to use its FetchContent functionality. Indeed, most repositories seem to require different treatment, and the rules of such treatment defy my comprehension.
That said, here is my problem. I would like to use CppADCodeGen in my project using CMake FetchContent. Here is my code:

[cmake] -- Configuring incomplete, errors occurred!
Is anyone able to achieve the above goal on their machine? If yes, would they kindly share how they did it? In the above error messages there are several errors, and I have already tried some solutions, but none of them worked -- I will not list them because they are no use mentioning!
EDIT
#dlivshen When I integrated my library with a bigger project, I had more problems due to conflicting target names. This is because I used FetchContent to get Eigen. So I decided to obtain it using ExternalProject, and for this purpose I added these lines to the CMakeLists.txt.in file you proposed in your solution:
ExternalProject_Add(
eigen
GIT_REPOSITORY https://gitlab.com/libeigen/eigen.git
GIT_TAG 3.4.0
GIT_SHALLOW TRUE
GIT_PROGRESS TRUE
CMAKE_CACHE_ARGS
-DCMAKE_INSTALL_PREFIX:STRING=${CMAKE_BINARY_DIR}/eigen
-DEIGEN_BUILD_DOC
OFF
-DBUILD_TESTING
OFF
-DEIGEN_LEAVE_TEST_IN_ALL_TARGET
OFF
-DEIGEN_BUILD_PKGCONFIG
OFF)
Then, in order to use Eigen I have to necessarily add ${CMAKE_BINARY_DIR}/eigen/include/eigen3 to the target_include_directories command. This is in contrast to when I used FetchContent whereby I only needed to add Eigen3::Eigen to the target_link_libraries command. This approach is not possible with ExternalProject: is this statement correct? If not, how can I achieve it?
Problems Overview
As seen in the output you've provided, there are 2 problems:
There is a target name conflict between probably CppAD and eigen. They both have the uninstall target. It can be seen here:
[cmake] CMake Error at build/_deps/cppad-src/CMakeLists.txt:452 (ADD_CUSTOM_TARGET):
[cmake] ADD_CUSTOM_TARGET cannot create target "uninstall" because another target
[cmake] with the same name already exists. The existing target is a custom target
[cmake] created in source directory
[cmake] "project/build/_deps/eigen-src".
cppadcodgen requires an already installed version of CppAD. It can be seen in the error message which tells us that an invalid version was found:
[cmake] CMake Error at build/_deps/cppadcodgen-src/cmake/FindCppAD.cmake:99 (MESSAGE):
[cmake] Found CppAD version '' but at least version '20200000.1' is required
[cmake] Call Stack (most recent call first):
[cmake] build/_deps/cppadcodgen-src/CMakeLists.txt:42 (FIND_PACKAGE)
Solution
Unfortunately, currently we can't use FetchContent to deal with those problems, because:
There isn't any mechanism that would allow us distinguishing conflicting targets (for example a "namespace" prefix could be a solution and then there could be 2 targets eigen:uninstall and cppad:uninstall).
We can't build the dependent target during configuration step.
Instead we'll use the ExternalProject module. Here's a possible solution:

I used the following commands to test it:
mkdir cmake-build
cd !$
cmake ..
cmake --build .
Explanation
Most of the parameters are exactly the same as used in FetchContent. The only differences are:
We install cppad to the build directory instead of a system wide directory, so the whole process will be self-contained. It is achieved by setting the cppad_prefix cache variable to ${CMAKE_BINARY_DIR}/cppad in the CMAKE_CACHE_ARGS option.
We make sure that cppadcodgen succeeds finding CppAD by setting the CPPAD_HOME cache variable to the include directory (which is ${CMAKE_BINARY_DIR}/cppad/include) and also setting this target to run after CppAD is installed using the DEPENDS option.
cppadcodgen sets the test targets as well and it will fail if it cannot find Google Test. Fortunately they provide an option to download Google Test using the GOOGLETEST_GIT option which we set to ON.
Finally, we set to install cppadcodgen inside the build directory, by setting CMAKE_INSTALL_PREFIX variable.
Note that I haven't touched eigen because I don't know what would be the exact usage and it didn't fail the build. It could be easily modified to be ExternalProject as written above if needed.
More information on ExternalProject can be found in Cmake's documentation.
Consuming the Dependencies
In order to consume the dependencies we have to perform some modifications.
Let's take as example the main file from CppADCodeGen wiki page and try to compile it with our solution:
main.cpp
#include <iosfwd>
#include <vector>
#include <cppad/cg.hpp>
using namespace CppAD;
using namespace CppAD::cg;
int main() {
// use a special object for source code generation
typedef CG<double> CGD;
typedef AD<CGD> ADCG;
/***************************************************************************
* the model
**************************************************************************/
// independent variable vector
CppAD::vector<ADCG> x(2);
x[0] = 2.;
x[1] = 3.;
Independent(x);
// dependent variable vector
CppAD::vector<ADCG> y(1);
// the model
ADCG a = x[0] / 1. + x[1] * x[1];
y[0] = a / 2;
ADFun<CGD> fun(x, y); // the model tape
/***************************************************************************
* Generate the C source code
**************************************************************************/
/**
* start the special steps for source code generation for a Jacobian
*/
CodeHandler<double> handler;
CppAD::vector<CGD> indVars(2);
handler.makeVariables(indVars);
CppAD::vector<CGD> jac = fun.SparseJacobian(indVars);
LanguageC<double> langC("double");
LangCDefaultVariableNameGenerator<double> nameGen;
std::ostringstream code;
handler.generateCode(code, langC, jac, nameGen);
std::cout << code.str();
}
Note that ExternalProject_Add command runs on build time, and we would like to find our dependencies already during Cmake reload time. So unfortunately we'll have to do a dirty trick to force ExternalProject_Add to run on Cmake reload time:
We'll move the ExternalProject_Add commands into a helper, CMakeLists.txt.in file.
We'll configure the CMakeLists.txt.in so the output paths of the libraries will remain inside our build directory.
We'll invoke execute_process (which run on cmake reload time) to execute the build process of the helper CMakeLists.txt.in
We'll find our libraries and consume them. Note that we can't use the modern Cmake targets syntax, as the whole process is being run in a sub-process and we don't have access to the created target. But even if we didn't run it inside a sub process, ExternalProject targets' type is utility which can't be used in commands such as target_link_libraries. So we'll use the custom paths we created for the dependencies and pass them to target_link_libraries and target_include_directories commands.
The end results are displayed below:

As before, I used the following commands to test it:
mkdir cmake-build
cd !$
cmake ..
cmake --build .
./main
The solution is based on this post.

Setting Ninja values through CMake (cross compilation)

I am currently trying to cross compile a program I wrote on macOS to Linux, and I have had to make some changes to the build.ninja file to make that possible (specifically the linker commands/other places where libraries are linked). However, this gets wiped when I reconfigure CMake. Is there a way that I could use CMake to set the values in my Ninja file instead of wherever they are being set from? I am also using vcpkg for this project with GCC 10.2.0 for x86_64 Linux. The ninja files had to be trimmed to fit under the character limit, I can find a different way to put up the complete ones if needed. Here are my current CMakeLists, the first being my top level one and the second being the one that links everything:
Removed to make room for edits, working file can be found in edit 2
# CMakeList.txt : CMake project for ImpromptuServer, include source and define
# project specific logic here.
#
cmake_minimum_required(VERSION 3.8)
add_subdirectory("database")
add_subdirectory("web")
add_subdirectory("api")
add_subdirectory("utils")
# Add source to this project's executable.
file(GLOB_RECURSE web ./web/*.cpp ./web/*.hpp)
file(GLOB_RECURSE database ./database/*.cpp ./datbase/*.hpp)
file(GLOB_RECURSE api ./api/*.cpp ./api/*.hpp)
add_library(libweb ${web})
add_library(libdata ${database})
add_library(libapi ${api})
add_executable(ImpromptuServer "ImpromptuServer.cpp" ${web} ${database} ${api})
set(ALL_LIBS Wt::Wt Wt::Dbo Wt::HTTP Wt::DboSqlite3 cryptopp-static json11 OpenSSL::SSL OpenSSL::Crypto cpr)
# TODO: Add tests and install targets if needed.
target_link_libraries(ImpromptuServer PRIVATE ${ALL_LIBS})
target_link_libraries(libweb PRIVATE Wt::Wt Wt::Dbo Wt::HTTP Wt::DboSqlite3)
target_link_libraries(libdata PRIVATE Wt::Wt Wt::Dbo Wt::HTTP Wt::DboSqlite3)
target_link_libraries(libapi PRIVATE ${ALL_LIBS})
I know GLOB_RECURSE is not best practice, but I don't want to change it unless it will fix my problem. Here is my original build.ninja file:
REMOVED due to irrelevancy to question.
Here is the one that I modified to get working:
REMOVED due to irrelevancy to question.
However, even when I compile successfully with the modified ninja file, I get this output message and the code fails to run on a Linux machine:
/Volumes/CaseSensitive/cross/lib/gcc/x86_64-linux/10.2.0/../../../../x86_64-linux/bin/ld: warning: cannot find entry symbol arch_paths_first; defaulting to 0000000000414000
The code runs fine when compiling for macOS and using the original build.ninja file.
Edit 1
After a lot of work, I have gotten CMake to use the toolchain file, but I still have a lingering problem where CMake can't find Threads::Threads. Here is my current CMakeLists.txt:
Working file can be found in edit 2

While all of the paths are system-specific, this could be improved later with some more advanced scripting. Here are the arguments I pass in on MacOS and Linux respectively:
-DCMAKE_TOOLCHAIN_FILE=/Users/jackhogan/Desktop/Code/Utilities/vcpkg/scripts/buildsystems/vcpkg.cmake -DUSE_LINUX=false
-DCMAKE_TOOLCHAIN_FILE=/Volumes/CaseSensitive/vcpkgLinux/scripts/buildsystems/vcpkg.cmake -DUSE_LINUX=true

CMake Errors -Using Conan in the yuzu generator

I am using vs code and CMake to generator the yuzu project, but the CMakeList.txt always report error on the conan code since line 127 ,and I have already install the conan in the CMD with pip command.

[cmake] CMake Error at CMakeLists.txt:252 (conan_check):
[cmake] Unknown CMake command "conan_check".
generally its a problem that the CMakeList.txt file can't run the code about the conan and the lib can't be auto download, but how can i sovle the porblem, bro??????The project do not offer the conan.cmake. im a web developer,not familiar with the c++ proj construct.
The CMakeLists.txt of the yuzu repository (found at the parent directory) requires version 1.24.0 of conan, while the latest is 1.25.2. I assume you have installed the latest version.
Change line 252 from:
conan_check(VERSION 1.24.0 REQUIRED)
to:
conan_check(VERSION 1.25.2 REQUIRED)
and it should work.
Do not forget to delete the cmake cache in your build folder.
