KDevelop: cmake parser performance

Hi Aleix,

I've done some basic profiling of the cmake parser's
performance using 
callgrind/kcachegrind, and I've found that much of the time
is spent in 
regular expression matching.

I haven't looked much into how the cmake support works, but
is it 
theoretically possible to reduce the dependency on regular
expressions?  It 
could potentially significantly speed things up (my modern
pc takes a few 
seconds to parse the kdevelop project's cmake files)

Cheers,
Hamish.

I noticed the same and planned to look into this soon. (It's
on my list after 
I finish the bugzilla templates)
