I tried something similar to this:
# include(CPack)
#
set(CPACK_...)
# include(CPack)
It did not work as expected.

It seems that
when including CPack the 2nd time, things like the version number are not
updated to the new values, probably because the variable is already set and
will not be automatically overwritten.

I assume that you'll suggest "set
the version number before first including CPack". And I will disagree there.
People would have to look at the sourcecode to figure out which values they
have to set before the first inclusion and which to set afterwards. From a
usability point of view this would be bad.

Kind regards,
Dennis
