GLOB with CONFIGURE_DEPENDS

Browse Source 
Globbing generally misses to pick up files which were added/deleted
after CMake's configure. This is a nuissance but can be alleviated using
CONFIGURE_DEPENDS (available since CMake 3.12) which adds a check for
new/deleted files before each compile and - if necessary - restarts the
configuration. On my system, the check takes < 0.1 sec.

(Side note: CONFIGURE_DEPENDS is not guaranteed to work accross all
generators, but at least it works for Ninja which everyone @CH seems to
use.)
