推荐答案

如果您的编译器支持添加到预处理器定义中(Visual Studio 2013中的屏幕截图):

If your compiler supports raw strings then you can add MYMACRO=R"($(ProjectDir))"; to preprocessor definitions (screenshot from Visual Studio 2013):

然后，您可以在代码中添加以下内容:

Then you can add the following to your code:

#pragma message("MYMACRO == " MYMACRO) // will print project dir during compilation


std::cout << MYMACRO << std::endl; //will print project dir at run time
