十月萌梦社区更新计划一览


  • 网站研运

    十月份,我们打算继续更新一下萌梦社区,首先需要做的就是主页部分的自动更新一览部分。也就是说,一旦有新的内容更新,那么我们会同步更新新的内容到我们的主页上,这样能够很自由,很方便地更新主页,而不是只有编辑选定的一种方法。

  • 首先我看到的就是option选项。这个选项在cmake中的文档是这样的:

    Now let us consider making the MathFunctions library optional. In this tutorial there really isn’t any reason to do so, but with larger libraries or libraries that rely on third party code you might want to. The first step is to add an option to the top level CMakeLists file.

    # should we use our own math functions? option (USE_MYMATH "Use tutorial provided math implementation" ON)

    This will show up in the CMake GUI with a default value of ON that the user can change as desired. This setting will be stored in the cache so that the user does not need to keep setting it each time they run CMake on this project. The next change is to make the build and linking of the MathFunctions library conditional. To do this we change the end of the top level CMakeLists file to look like the following:

    # add the MathFunctions library? # if (USE_MYMATH) include_directories ("${PROJECT_SOURCE_DIR}/MathFunctions") add_subdirectory (MathFunctions) set (EXTRA_LIBS ${EXTRA_LIBS} MathFunctions) endif (USE_MYMATH) # add the executable add_executable (Tutorial tutorial.cxx) target_link_libraries (Tutorial ${EXTRA_LIBS}) 参考来源:这里

    在我看来,cmake中的option命令更像是一个宏,规定了是否定义这个宏以及这个宏所带来的连锁反应。option规定的这个宏,通过ON的设定来表示是否定义。
