[CMake] Save stripped debugging information

[Lukas Anzinger]

Hi,

I'm aware of the option CMAKE_BUILD_TYPE with which I can tell if I
want to include debugging information or not.

A very useful feature of the program objcopy is, to not strip
debugging information from a file but to split it from it so that you
can release a program without debugging information but can later
debug it if you put the split debugging files in certain directories
(more at http://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html).

Is there a CMake way to do this?

Regards,

Lukas
