cmake的-D <var>：<type> = <value>：有什麼可以<type>呢？

Question

-D <var>:<type>=<value>：創建cmake緩存條目。

確定，但有什麼可以<type>呢？我見過BOOL，STRING，PATH，FILEPATH。該類型還有什麼？

從CMake的手冊頁，在 「上高速緩存條目屬性」：

TYPE Widget type for entry in GUIs. 

    Cache entry values are always strings, but CMake GUIs present widgets to help users set values. The GUIs use this property as a hint to determine the widget type. Valid TYPE values are: 

      BOOL   = Boolean ON/OFF value. 
      PATH   = Path to a directory. 
      FILEPATH  = Path to a file. 
      STRING  = Generic string value. 
      INTERNAL  = Do not present in GUI at all. 
      STATIC  = Value managed by CMake, do not change. 
      UNINITIALIZED = Type not yet specified. 

      Generally the TYPE of a cache entry should be set by the command which creates it (set, option, find_library, etc.).
