[CMake] Perl Compatible Regular Expressions. Why bother?

[Brandon Van Every]

Ok, having been informed of the ultimate CMake language strategy...

2 months ago, a fellow and I talked about possibly putting PCRE into
CMake.  I looked at the PCRE library the other day.  I was surprised
at how vast it was.  Tons of capabilities.  A handful of customizable
compilation defaults, which in permutation could confuse just about
anyone as to basic expected behavior.  At least there are options to
declare "I want exactly this kind of behavior" in the regex itself,
but boy, what a lot of blah blah blah.

Why bother to "improve" CMake with this?  I'm guessing I'm one of the
only people who has gone off the regex deep end with CMake, and that
almost no one else cares about these capabilities.  I don't even know
if I will care past my current project.
