You can modify the CMAKE_CXX_FLAGS_<Build Type> and/orCMAKE_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") If your CMake flags already contain/MD, you can ensure that the above commands are executed after the point at which/MDis inserted (the later addition of/MToverrides the conflicting existing option), or you can set the flags from scratch: set(CMAKE_CXX_FLAGS_RELEASE "/MT") set(CMAKE_CXX_FLAGS_DEBUG "/MTd") Or alternatively, you could replace the existing/MDand/MDdvalues with/MTand/MTdrespectively 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()
