TYPE — CMake 3.19.6 Documentation

# 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.).
