It was added by commit 496ec6036f (Help: Add Sphinx 'versionadded'
directives to each top-level document, 2020-07-06, v3.19.0-rc1~558^2)
because the document happened to be added during the 3.9 release series,
but the variable has existed since the beginning.

CMAKE_MATCH_<n>
|
|
---------------
|
|
|
|
Capture group ``<n>`` matched by the last regular expression, for groups
|
|
0 through 9. Group 0 is the entire match. Groups 1 through 9 are the
|
|
subexpressions captured by ``()`` syntax.
|
|
|
|
When a regular expression match is used, CMake fills in ``CMAKE_MATCH_<n>``
|
|
variables with the match contents. The :variable:`CMAKE_MATCH_COUNT`
|
|
variable holds the number of match expressions when these are filled.
