Sandro,

You may find this thread interesting:

http://lists.gnu.org/archive/html/automake/2009-05/msg00145.html

The GraphicsMagick's version.sh is interesting solution.

Simply, there are two cases where version info is used/generated:

1) Static version info stored currently in multiple places
(./configure, nmake.opt, CMakeLists.txt)
What about having such 'static' version info stored in plain text file
e.g. VERSION with number per line.

Then, this file could be parsed by ./configure, by cmake script and
even by NMAKE stuff too
so the general version info is consistent across all build configurations.

2) Volatile VCS-based version
In case of SVN/Git revision, version.sh could do this job as well for
./configure (see GraphicsMagick),
and native CMake scripting/modules could be used for CMake configuration.
For NMAKE, there could be simple .bat script.
