Sorry as my post was not clear enough. I think my problem is not cmake specific. But may be I can get some better solution here.
Using CMake I am generating a common version file. version.h which contains current svn version of source code. In all application main.c I am including this file. Now every application is depending on this version.h and everything got rebuild. I want to change this logic so application will have their own version and version.h file should be generated only if any other dependency of application is changed.
