[CMake] Why SET() not support regular expression ?

[David Cole]

If you do a FILE(GLOB cmake will not detect when files are added to the
directory and will *not* re-run automatically. If you explicitly list your
files in CMakeLists.txt, then when it changes, cmake re-runs automatically
as part of a build.

Don't use the FILE(GLOB technique unless you are willing to live with this
fact...

HTH,
David
