[CMake] Linking several executables to the same object files

[Daniel Gruen]

Hi there,

I'm new to cmake and currently about to migrate a majority of my software 
projects, as I really like it :)

Just one question: I have a project including several executables that all 
link to a set of common .o files (and I don't want to make a library out of 
it). Is there a way to prevent cmake from compiling them over and over again? 
Currently, it does (just having specified all the add_executables(something1 
commonfile1.cpp commonfile2.cpp commonfile3.cpp something1.cpp)), and the 
common source files will be compiled into object files for every executable 
anew, taking quite a lot more time than with simple commonfile.o targets in 
the previous Makefile.

Greetings & Thanks in advance

Daniel
