CMAKE_CXX_COMPILER_ID 变量可以直接作为字符串变量传给宏 add_executable(main) file(GLOB sources CONFIGURE_DEPENDS *.cpp *.h) target_sources(main PUBLIC ${sources}) target_compile_definitions(main PUBLIC MY_NAME="The ${CMAKE_CXX_COMPILER_ID} Compiler") 在程序运行后,就会输出:Hello, The GNU ...
CMAKE_CXX_COMPILER_ID: 编译器的 ID,例如"MSVC","GNU","Clang" CMAKE_GENERATOR: 构建系统 CMAKE_BUILD_TYPE: 构建模式,debug/release 等 CMAKE_CXX_STANDARD: c++标准,例如 20 代表 c++20 CMAKE_CXX_STANDARD_REQUIRED: 布尔变量,是否严格要求满足 c++标准 CMAKE_DEBUG_POSTFIX: debug 模式下会给生成的...

为了适应这一点,我们不得不将“Intel”的案例从IS_INTEL_CXX_COMPILER更改为IS_Intel_FORTRAN_COMPILER。我们可以通过使用相应的CMAKE_C_COMPILER_ID和CMAKE_CXX_COMPILER_ID变量为 C 或 C++实现相同的效果。但是请注意,CMAKE_<LANG>_COMPILER_ID并不保证为所有编译器或语言定义。
