Hello! I am attempting to CMake FreeGLUT on 64-bit Windows, and I’m running into some issues.
I created a build/ directory and ran the following command:
cmake.exe -G "MinGW Makefiles" -DCMAKE_C_COMPILER=C:\\msys64\\mingw64\\bin\\gcc.exe ..
CMake Deprecation Warning at CMakeLists.txt:1 (CMAKE_MINIMUM_REQUIRED):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.
Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.

You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_C_COMPILER= C:\\msys64\\mingw64\\bin\\gcc.exe

CMake Generate step failed. Build files cannot be regenerated correctly.
Okay, that’s my bad. Windows needs \\ for directories. But, in the build directory, and at the top level directory, I cannot find the cache file in order to delete it:

Can anyone assist me in finding this file so I can delete it and regenerate it? It’s nowhere in the freeGLUT directory that I can see.
Thank you in advance!
