Comment(by snc@…):

 Replying to [comment:13 tre@…]:
 > Mmh. Doesn't come Mac OS X with a preinstalled python binary? Do I
 really need a dependency?

 You don't absolutely have to but what happens as various versions from
 MacPorts are found, Python 2.4 through Python 3.2? If you don't mark a
 dependency on a MacPorts one and it was used, then uninstalling that
 Python could break your program since it may expect it (do you use Python
 outside of building?).

 > And if, I'm not really sure how to say cmake that it should search for a
 certain python version, I can only see that one can access the version
 number of the interpreter found.

 In KDE we do this by setting CMake's variables for the path of library and
 includes directories:
 {{{
 -DGETTEXT_INCLUDE_DIR=${prefix}/include
 -DGETTEXT_LIBRARY=${prefix}/libgettextlib.dylib
 }}}
