100% of Xcode users that use ctest to build.  I would still put that
in the 1% of those that build with CMake. A build with CMake does not
go via ctest, but is built on the command line or in the IDE Xcode
which will not have the regex slow down.

Changing just ctest somehow is a much smaller scope than changing
every regex in all of CMake.  I stand by my 99% are OK with the regex
that they have.  :)
