I think we can assume:

1) Those who would use cmake to build Kicad also have BZR installed.

2) Those who would use BZR also have python installed.

Therefore we can assume python at a version necessary to run BZR is
installed within the CMakeLists.txt script, but may not be in the PATH.

Could someone (you?) write a simple python "eval" type statement to get
these strings?  Then we can use a CMake macro to chain load python for
such values.

Here was somebody doing something similar with perl:


I would see no harm in enabling other CPack "targets" for CMake, as long
as they did not unconditionally fire when running CMake.  The Doxygen
target is one such optional cmake target.
