我在编译一个非常简单的CMakeLists.txt
时就明白了C:\Users\LZ\sw\test\integrations\cmake\tess>cmake -G "MinGW Makefiles" .
-- The CXX compiler identification is unknown

CMake Error at C:/Program Files/CMake/share/cmake-3.17/Modules/CMakeTestCXXCompiler.cmake:53 (message):
The C++ compiler
"C:/MinGW/bin/g++.exe"
is not able to compile a simple test program.
It fails with the following output:

即使我未在CMakeLists.txt中指定交叉编译，MinGW似乎也认为我正在交叉编译。或者它只是尝试一些交叉编译的东西，但是错误的原因就在于另一件事。
我正在PowerShell上运行它。我也尝试了cmd.exe。它可以在MSYS2的MinGW64 shell上运行，但这与C:/MinGW/bin/g++.exe没有关系，我不能使用其他shell，因为它抱怨sw.exe在路径中，我无法取出它因为我必须运行sw setup。
我该如何解决这个问题？
