CMAKE error: "Cannot open source file" : 'CMakeCCompilerId.c'

I am trying to run a CMAKE project that works on Windows and on Linux. When I try to run CMAKE to generate the build files I get the following error:

enter image description here

I checked other posts for this error, most of which suggested reinstalling Visual Studio, but that did not help.

Checking the error logs gave me this:

Compiling the C compiler identification source file "CMakeCCompilerId.c" failed.

The output was:

Does anyone know how I can solve the c1 : fatal error C1083: Cannot open source file: 'CMakeCCompilerId.c': No such file or directory error?

I had the same exact issue.

After following @serg06 link to the partial solution (and translating it from Chinese) I have found the solution for me:

I was using git from WSL and cmake from cmd, not sure why that is a problem, but installing git for windows and recloning my repo from cmd fixed the issue. Hope that helps!

After 3 hours of searching, I finally found a (partial) solution. All it says is:

  • Copy paste your project folder (the one with CMakeLists.txt) to your desktop.
  • Navigate there and run your cmake command again.
  • It works!

Why does it work on the desktop but not in its original position? No clue. I thought it was a permissions problem, so I MAXED out the permissions on my original folder. (Gave "Everyone" and myself full permissions + gave myself folder & subfolder ownership.) No difference.

Guess we'll just have to settle with having my project somewhere under C:\Users\Myname\.

If that doesn't solve your problem, some other solutions I found were:

  • Reinstalling cmake
  • Downgrading cmake to 3.14.x
  • Reinstalling VS
  • Making sure to specify the correct makefile generator. (E.g. if you call cmake -G "Visual Studio 12" ., you're referring to VS 2013 (VS 12 = VS 2013). See cmake --help for all generators.)
