我使用提供的CMakeLists.txt文件,其中包含上述代码。我想要做的是使用/ MT标志编译库。有人知道怎么做吗?
提前致谢,

向CMAKE_C_FLAGS和朋友添加标志是将特定标志传递给编译器的正确方法,但CMAKE_C_ *变量只影响C文件的编译。
如果项目中有任何C ++文件,您还需要设置CMAKE_CXX_FLAGS和朋友。
此外,您可以在不修改cake-gui或ccmake中的CMakeLists文件的情况下执行此操作。配置一次后,您可以在cmake-gui或ccmake中查看这些变量的默认值。然后,您可以直接在应用程序中更改一些变量,再次配置,并且瞧:您已经为构建树设置了标志而没有修改任何代码。
如果您总是想要标志,那么修改代码是正确的方法。但是如果你只是想完成一个构建,你可以设置标志而不需要触及代码。
