Hello Alex,

Do you mean grepping or globbing? Both can be done at configuration time
using the FILE command. You could perform a file(glob) followed by a
file(strings) in a loop. I'm not sure what you mean by cmake build time.
Cmake will generate a buildsystem (configuration time) and the
buildsystem will do the actual building (build time).

Regards,
Micha
