[CMake] Need help with GLOB expression

[Robert Dailey]

Thanks. I'll give this a try.
This isn't very intuitive, though. I was hoping for something a little less
redundant. Because now I have to do this:

file( GLOB_RECURSE
sources "C:\foo\bar\source\*.h" "C:\foo\bar\source\*.ipp"
"C:\foo\bar\source\*.hpp"
)

It just amazes me that this area of CMake is such a mystery.
