[CMake] Need help with GLOB expression

[Robert Dailey]

I would prefer it just work. For large directory hierarchies, running the
glob twice is severely inefficient.
Thanks for the link to the documentation. Can anyone figure out a way to
glob for H, HPP, and IPP files in a single glob operation? Is it even
possible? I'd be really disappointed it it wasn't.
