Question

我正在尝试使用mingw最新工具链和clang编译器（来自CLion IDE）在命令行选项中使用明确指定的编译器在win10下构建项目：

-DCMAKE_C_COMPILER=C:/dev/tools/LLVM/bin/clang.exe
-DCMAKE_CXX_COMPILER=C:/dev/tools/LLVM/bin/clang++.exe

cmake正确识别clang，但在测试期间编译尝试传递cl（Visual C ++编译器）标志：

C:\dev\tools\CLion.RC\bin\cmake\bin\cmake.exe -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=C:/dev/tools/LLVM/bin/clang.exe -DCMAKE_CXX_COMPILER=C:/dev/tools/LLVM/bin/clang++.exe -G "CodeBlocks - MinGW Makefiles" C:\Users\amigo421\ClionProjects\hr2

-- The C compiler identification is unknown
-- The CXX compiler identification is Clang 3.9.0
-- Check for working C compiler: C:/dev/tools/LLVM/bin/clang.exe
-- Check for working C compiler: C:/dev/tools/LLVM/bin/clang.exe -- broken CMake Error at

(message):   The C compiler "C:/dev/tools/LLVM/bin/clang.exe" is not
able to compile a   simple test program.

  It fails with the following output:

  C:\dev\tools\LLVM\bin\clang.exe /DWIN32 /D_WINDOWS /W3 -o  
CMakeFiles\cmTC_397ea.dir\testCCompiler.c.obj -c

你看到cmake传递了visual c ++标志，我不打算使用clang-cl。我想cmake应该在命令行中使用GCC（MinGW）参数

任何想法如何解决这个问题

CMake将Visual C ++参数传递给clang而不是被驱逐的GCC参数
