打算将论坛添加发帖的头衔
-
比如说，论坛的发帖者是来自管理员、专栏作者还是其它人物，可以在帖子的内容最开头的地方注明。
比如说这个论坛：
-
@jiangcaiyang123 可以可以可以~
-
运营策略中授予头衔是一个很好的策略。可以激励论坛坛友继续为论坛的更好发展而努力，也可以让游客认为我们论坛非常棒，更重要的是论坛会变得很好看。
我们可以参考一下一些动漫论坛中头衔的设置：
-
新的论坛已经拥有管理员的聊天室了！

看到过很多代码都有用这个

做得还不错的嘛。希望继续呢。

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。
