I have several modules managed with cmake and a script to build all
the modules at once. When a simple module gets modified, cmake
rebuilds what is needed in it and copies the API files in the include
path. Those API files' date get modified at this time, resulting on
the rebuild off all modules depending on this first simple module. My
wish would be to avoid date change at copy time to free some time
during build process. (copies are made thanks to cmake command mode
calls)
The best thing to do would be a copy if different. If the files really
do change, then you would want a rebuild. Both configure file and -E
copy_if_different will work.
