我正在尝试使用CMake为Windows 10编译Assimp 5.0.1。我在MinGW中使用的C/C++编译器是GCC和G++。若我正确地理解了这个问题，那个么MakeFile的空白就有问题了。/CMakeTmp/目录是空的，我相信答案就在我面前：
控制台输出：
-- 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

It fails with the following output:

cmake使用了哪个-G选项？make的/nologo参数似乎不对，看起来像是Microsoft/MSVC参数。如果未指定-G，则CMake在Windows上默认为-G"NMake Makefiles"。
如果使用MSYS的make，请确保对mingw32-make或-G"MSYS Makefiles"使用cmake标志-G"MinGW Makefiles"。
但是，为了避免所有这些问题并提高速度，-GNinja是最好的解决方案，前提是您有可用的忍者(请参阅https://ninja-build.org/)。
最后，您仍然使用MinGW GCC 9.2.0。有更新的版本，请参阅http://winlibs.com/对于也带有更新的CCD_ 13的独立构建。
