Subject: [PATCH] Fix configure on macOS x.y.z when y is 0
The "Could not run sw_vers" error is output when building on macOS x.y.z
when y is 0 (example: macOS 12.0.1) because CMAKE_MATCH_2 is set to "0",
which when used as a condition evaluates to false.
Check `CMAKE_MATCH_COUNT EQUAL 2` instead to know whether CMAKE_MATCH_1
and CMAKE_MATCH_2 are properly set.
