相关疑难解决方法(0)

我按照CMake FAQ条目"如何使用静态运行时构建我的MSVC应用程序？"中的说明进行操作.集中选择一组嵌套的CMake项目的MSVC运行时(它们作为Git子模块引入并使用CMake find_package()指令添加到主项目中).

所以,我写了这个CMake宏:

macro(configure_msvc_runtime)
  if(MSVC)

    # Default to statically-linked runtime.
    if("${MSVC_RUNTIME}" STREQUAL "")
      set(MSVC_RUNTIME "static")
    endif()

    # Set compiler options.
    set(variables
      CMAKE_C_FLAGS_DEBUG
      CMAKE_C_FLAGS_MINSIZEREL
      CMAKE_C_FLAGS_RELEASE
      CMAKE_C_FLAGS_RELWITHDEBINFO
      CMAKE_CXX_FLAGS_DEBUG
      CMAKE_CXX_FLAGS_MINSIZEREL
      CMAKE_CXX_FLAGS_RELEASE
      CMAKE_CXX_FLAGS_RELWITHDEBINFO
    )
    if(${MSVC_RUNTIME} STREQUAL "static")
      message(STATUS
        "MSVC -> forcing use of statically-linked runtime."
      )
      foreach(variable ${variables})
        if(${variable} MATCHES "/MD")
          string(REGEX REPLACE "/MD" "/MT" ${variable} "${${variable}}")
        endif()
      endforeach()
    else()
      message(STATUS
        "MSVC -> forcing use of dynamically-linked runtime."
      )
      foreach(variable ${variables})
        if(${variable} MATCHES "/MT")
          string(REGEX REPLACE "/MT" "/MD" ${variable} "${${variable}}") …
