is" $ENV{myenv}) 在上述示例3的CMakeLists.txt中是有两个展示阶段:第一将在配置期间打印myenv环境变量并通过add_custom_target() 添加一个构建阶段,第二将在构建阶段过程中打印相同的变量。构建上述CMakeLists.txt通过一个bash脚本文件执行,见下:
CMAKE_CXX_COMPILER 与CMAKE_C_COMPILER类似,不过这个变量对应的环境变量是CXX,是编译C++语言的编译器。 结果如下: $ cmake .. -- The C compiler identification is GNU 8.3.0 -- The CXX compiler identification is GNU 8.3.0 ... 1. 2.
-- The CXX compiler identification is GNU 7.5.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done
在这种情况下,如果最新的编译器不在系统当中(在这个例子中,GNU GCC 11),用户将只看到以下消息,并且构建将停止: Target "Standard" requires the language dialect "CXX23" (with compiler extensions), but CMake does not know the compile flags to use to enable it. ...
