CMAKE_MATCH_COUNT

.. versionadded:: 3.2

The number of matches with the last regular expression.

When a regular expression match is used, CMake fills in :variable:CMAKE_MATCH_<n> variables with the match contents. The CMAKE_MATCH_COUNT variable holds the number of match expressions when these are filled.
