Is this a cache variable or a regular variable? Cache
variables have<br>
this enum-like support in the form of the STRINGS property.
Example:<br>
<br>
set(MYSTRING "A" CACHE STRING "Documentation for the
variable")<br>
set_property(CACHE MYSTRING PROPERTY STRINGS "A;B")<br>

<div>Note that this isn't an enforcing feature, only a
convenience for CMake GUI and ccmake. It tells those tools
what to show as selectable options for that cache variable,
but you can still set the variable to anything you like via
the cmake -D command line option or in the project itself.</div>
