Assimp Compilation Error Using CMake: GCC Cannot Compile Test Program

I am trying to compile Assimp 5.0.1 for Windows 10 using CMake. The C/C++ compilers I have through MinGW are GCC and G++. If I understand the problem correctly, there is an issue with the MakeFile's whitespace somewhere. The /CMakeTmp/ directory is empty, and I am sure the answer is right in front of me somewhere:

Console Output:

-- The C compiler identification is GNU 9.2.0
-- The CXX compiler identification is GNU 9.2.0
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - failed
-- Check for working C compiler: C:/MinGW/bin/gcc.exe
-- Check for working C compiler: C:/MinGW/bin/gcc.exe - broken
CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.20/Modules/CMakeTestCCompiler.cmake:66 (message):
  The C compiler

    "C:/MinGW/bin/gcc.exe"

  is not able to compile a simple test program.

  It fails with the following output:

    Change Dir: Q:/programming/westy/src/lib/assimp-5.0.1/build/CMakeFiles/CMakeTmp

    Run Build Command(s):make -f Makefile /nologo cmTC_a4ec5\fast && Makefile:37: *** missing separator.  Stop.

Which -G option did you use for cmake? The /nologo parameter for make doesn't seem right, that looks like a Microsoft/MSVC parameter. If you didn't specify -G then CMake defaults to -G"NMake Makefiles" on Windows.

Make sure to use cmake flag -G"MinGW Makefiles" for mingw32-make or -G"MSYS Makefiles" if you use MSYS' make.

But to avoid all those make issues and improve speed -GNinja is the best solution, provided you have Ninja available (see https://ninja-build.org/).

Finally, you're still on MinGW GCC 9.2.0. Newer versions are available, see http://winlibs.com/ for standalone builds which also come with newer mingw32-make.
