[CMake] Need help with GLOB expression

[Carlson Daniel]

Ok, I thought that Cmake supported the standard regular expression used by
most GNU projects. The |-sign is an or-operator so the standard regular
expression for this would be:

^.*\.(h|hpp|ipp)$

but now I realize that global expression and regular expression is not the
same thing... Sorry for that!
