Currently KiCad uses a configure file mechanism for the version.h file
and it's not normal to regenerate these each time you make otherwise
you end up re-compiling everything that uses the file and then
re-linking everything that links to that target if the target's a
library (which in this case it is).

Therefore, when you bzr up - make rebuild_cache too in order to update
the version number. Caching this value makes subsequent repetitive
builds quicker. If you can suffer the time, just do a simple cheat:

bk.sh
    #!/bin/bash
    make rebuild_cache
    make

just use bk.sh instead of make...

The following is from CMakeModules/version.h.cmake :

/*
 * Define the current source code Subversion commit number.  The version
 * string defined below does not update automatically when building the
 * source with make.  Run make rebuild_cache to update version strings.
 */
