Not able to build a Qt project in visual studio 2005 - c++

When i am building my project in visual studio 2005 its end up with the following error
fatal error LNK1181: cannot open input file 'QtCored.lib'.
Please let me know where i am failing .

When we are integrating Qt 4.7.3 with visual studio 2005 and tries to create one Qt project in IDE , its giving a fatal error stating Qtcored.lib is missing . Actually if you go ..\Qt\4.7.3\lib folder there is nothing called Qtcored.lib ,But there is Qtcored4.lib . I think they have renamed it (not sure) . Now goto projproperties->linker->input->additionaldependency and remove Qtcored.lib from there and add Qtcored4.lib. Now if you build the project it will work fine ..
Cheerssss.. :)

Visual studio is not able to find the library file QtCored.lib. You have to specify the library path of it in visual studio settings.

"LINK : fatal error LNK1104: cannot open file 'm.lib'" when trying to build a C++ project on Windows

I am trying to build a C++ project on Windows using Visual Studio Code. I've installed the C++ compilers and libraries using the Visual Studio Build Tools.
I searched for the m.lib, but I can't find it and I am not sure where should it be.
The only similar issue I found here but I don't have a build.ninja folder

TightVNC on VS2015 compile from source code

I am trying to compile the TightVNC from the source code.
Here is my system details:
Windows 10
SDK 8.1
When i build the project it throw error about the folder or file not found. I try to install and include the files but it won't worked.
sidenote: I am not a C++ developer, i have to compile it from source code.
Thanks in advance.
The error
RC1015 can't open include file afxres.h
seems to generate from project because it requires the header file from MFC. As far as I understand, visual studio 2015 default setup does not install Visual C++ MFC package. Therefore you need to modify the Visual Studio 2015 setup and add the MFC.
Please close VS2015 and Go To
Control Panel->Programs and Features->
Microsoft Visual Studio <Professional/Enterprise>->
Change->Modify->Add Microsoft Foundation Classes
Then re-open visual studio 2015 and re-build the solution.

LNK1104 cannot open file '...lib.obj'

I'm trying to update Visual Studio 2012 C++ projects so that I can compile them in Visual Studio 2015 (Update 3). I've gotten it narrowed down to just one error in one project that I'm completely stumped on:
LNK1104 cannot open file 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\lib.obj'
I've installed all the C++ language options (they don't get installed by default) and even uninstalled and reinstalled Visual Studio.
That file doesn't exist in that directory, and it also doesn't exist in the Visual Studio 2012 directory either.
Anyone have any ideas on how to solve this?
The problem might be that you added something like "$(VC_LibraryPath_x86)xxxx.lib" to the Linker input additional dependencies. This goes wrong, resulting in the error. It should just be "xxxx.lib".
Check your path. If that's correct then make sure you've written xxx.lib rather than xxx

Getting "Cannot open include file: 'atlbase.h': No such file or directory" error

I am swapping machines (between two Windows 8.1 laptops) and have just loaded the project I'm working on from TFS. On one machine it compiles, on the other it does not and gives the first error
error C1083: Cannot open include file: 'atlbase.h': No such file or directory
On both laptops I am running Visual Studio Ultimate 2013. On the first laptop I've checked to see where it is picking up atlbase.h and it is from C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\atlmfc\include i.e. from the Visual Studio 2012 installation directory. On the new machine I do not have Visual Studio 2012 installed so the directory C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\atlmfc\include does not exist.
Other people have similar problems (e.g. Ramilol's question) because they are using Visual Studio Express. I am using Ultimate.
It could be an environment variables problem (as suggested by raj raj) but my include directory paths under VC++ Directories are $(VCInstallDir)include;$(VCInstallDir)atlmfc\include;$(WindowsSDK_IncludePath) as required.
My general question is "how do I fix this?" but I'd also be interested to know how I check and set the value of $(VCInstallDir) since C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\atlmfc\include does have atlbase.h in (so I am flummoxed as to why it is not picked up).
========== EDIT 1: Rewording ==========
Let me have another go at wording this question.
I have loaded a Visual Studio 2013 project onto a new build laptop from TFS. It will not build and gives errors like error C1083: Cannot open include file: 'atlbase.h': No such file or directory. The file atlbase.h is present on the new machine, in the directory C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\atlmfc\include.
In my project's properties my include directory paths under VC++ Directories are $(VCInstallDir)include;$(VCInstallDir)atlmfc\include;$(WindowsSDK_IncludePath)
How do I check what those macros are set to, and if they are not where atlbase.h is (i.e. C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\atlmfc\include) how do I fix that?
========== EDIT 2: Microsoft Visual C++ Redistributables installed ==========
Responding to jp2code's answer the machine that works and the one that does not have a similar array of Microsoft Visual C++ Redistributables installed as the following screenshot shows (the working machine's on the left):
========== EDIT 3: Environment variables ==========
In his answer, pje explains how to look up the environment variables. %VCInstallDir% is correctly set to C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\ But if I right click on the line #include <atlbase.h> I get this error which suggests that despite %VCInstallDir% being correct, that is not where VS is looking:
========== EDIT 4: Platform toolkit setting ==========
Another possibility is the Configuration Properties | General | Platform Toolset project setting, suggested by manuell in the comments and Michael Burr in his answer. For the project it is set to set to Visual Studio 2012 (v110) but the only other option listed in the drop-down is v110_wp80, which, when selected, becomes Windows Phone 8.0 (v110). If I hand edit the .vcxproj file in notepad and reopening the project in Visual Studio Ultimate 2013 the property page now lists the Platform Toolset as Visual Studio 2013 (v120) (not installed).
If I start a new C++ Windows Store project I can set Platform Toolset to Visual Studio 2013 (v120) without issue, in fact it is the only option listed in the drop-down. (N.B. The new project has Target Platform Version set to 'Windows 8.1', and it is greyed out, so I cannot change it, while the failing project has it set to Windows 8.)
========== EDIT 5: Entire project settings file ==========
In the comments Michael suggests that "maybe posting the .vcxproj somewhere (like as a gist on github) might be helpful". I have posted it here.
========== EDIT 6: Uninstalling and reinstalling Visual Studio 2013 Ultimate ==========
Has no effect, the same error recurs.
On the new machine I do not have Visual Studio 2012 installed
Well, look no further, that's your problem. Your project targets the VS2012 toolset to build a Store project that runs on Windows 8.0. You can still open it in VS2013 but it can only be built if you have VS2012 installed as well. In other words, you must have the v110 toolset available on the machine. You don't.
Short from installing VS2012, you will have to re-target to 8.1 to get it to build with the VS2013 toolset (v120). Right-click the Solution node in the Solution Explorer window and select "Retarget Windows Store projects to Windows 8.1".
Do fret a bit about that laptop, it remembers too much about VS2012. Sounds like it had it once installed but it wasn't uninstalled properly.
If you want to see the value of $(VCInstallDir) or any other Visual Studio macro, then open the Developer Command Prompt for VS2013 (this should have installed with your VS 2013 install). In the prompt type: echo %VCInstallDir%. This will print the current value of the $(VCInstallDir) macro. If you want to change this to a different directory, then type set VCInstallDir=<directory path>, where <directory path> is the path to your desired directory (presumably C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\atlmfc\include in your case).
Hope this helps, cheers!
------edit-------
As a side note, it is possible that these macros were imported with the 2012 project that you were trying to load and compile with 2013. If it turns out that it was your $(VCInstallDir) macro that was wrong, then that would explain why.
Check that the "Configuration Properties | General | Platform Toolset" project setting is:
Visual Studio 2013 (v12)
and not something like "Visual Studio 2012 (v110)
Possible solution
Get Process Monitor
Filter for atlbase.h
this way you will know exactly where Visual Studio is looking for atlbase.h. Process monitor will show you the failed file-open attempts.
At this point you will be able to solve the problem by
make symbolic links (messy)
fix the include directory paths (better)
Update
Here is how you filter for file operations:
Don't forget to click Add after setting the filter parameters.
Check to see that both machines have the same versions of C++ Redistributable installed.
It is worth a shot, and will be easy to check.

Qt Visual Studio 2008 Add-in problem

I have Qt 2009.05 and Qt VS Add-in 1.1.3 installed on my computer with Visual Studio 2008. When I create simple Qt Application and build it, I'm receiveing this error.
1>LINK : fatal error LNK1181: cannot open input file 'qtmain.lib'
When I searched whole disk this file to add in Visual Studio library include variable, I doesn't find. I have qtmain.prl in my qt/lib directory but not qtmain.lib...
Your qt\lib directory should contain all the lib files. You have probably downloaded qt source package but you haven't built it. Download pre-built version for Visual Studio from here.
