CMake用/ MT编译，而不是/ MD

问题描述：

我在windows上使用cmake与Windows SDK和NMake Makefiles

I'm using cmake on windows with the Windows SDK and NMake Makefiles

默认情况下，它编译/ MD编译器开关。

By default it compiles with the /MD compiler switch.

我如何改变它用/ MT开关编译？

How can I change it to compile with the /MT switch instead?

答

您可以修改 CMAKE_CXX_FLAGS_< Build Type> 和/或 CMAKE_C_FLAGS_< Build Type> 变量：

You can modify the CMAKE_CXX_FLAGS_<Build Type> and/or CMAKE_C_FLAGS_<Build Type> variables:

set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT")
set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /MTd")

如果您的CMake标志已经包含 MD ，您可以确保在 / MD 插入之后之后执行上述命令添加 / MT 覆盖冲突的现有选项），或者您可以从头设置标记：

If your CMake flags already contain /MD, you can ensure that the above commands are executed after the point at which /MD is inserted (the later addition of /MT overrides the conflicting existing option), or you can set the flags from scratch:

set(CMAKE_CXX_FLAGS_RELEASE "/MT")
set(CMAKE_CXX_FLAGS_DEBUG "/MTd")

b $ b

或者，您可以用 / MD 和 / MDd $ c> / MT 和 / MTd 分别执行以下操作：

Or alternatively, you could replace the existing /MD and /MDd values with /MT and /MTd respectively by doing something like:

set(CompilerFlags
        CMAKE_CXX_FLAGS
        CMAKE_CXX_FLAGS_DEBUG
        CMAKE_CXX_FLAGS_RELEASE
        CMAKE_C_FLAGS
        CMAKE_C_FLAGS_DEBUG
        CMAKE_C_FLAGS_RELEASE
        )
foreach(CompilerFlag ${CompilerFlags})
  string(REPLACE "/MD" "/MT" ${CompilerFlag} "${${CompilerFlag}}")
endforeach()
