Revise docs for all "Scripting Commands", except four find_XXX that use a macro suite of their own. * Take full advantage of the improved syntax highlighting. * Make consequential use of <..> placeholders. * Clarify things here and there in the text. Specific improvements to some command docs: * "math": Correct description of novel hexadecimal capability. * "if", "foreach", "while": Provide link to "endif" etc * "foreach", "while": Mention "break" and "continue". * "foreach": Simplify explanation of ``RANGE`` and ``IN`` signatures; advise against negative arguments or reverse ranges (compare issue #18461) * "endif", "endfunction" etc: Explain that the argument is optional and maintained for compatibility only

|
|
Get a property of ``DIRECTORY`` scope.

get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)
|
|

The ``DIRECTORY`` argument specifies another directory from which

|
|
The specified directory must have already been traversed by CMake.

If the property is not defined for the nominated directory scope,
|
|
an empty string is returned. In the case of ``INHERITED`` properties,
|

if the property is not found for the nominated directory scope,
|
|
the search will chain to a parent scope as described for the
|
|
:command:`define_property` command.
