hi Rene,

The semicolon is almost certainly causing the problem.  The semicolon
is CMake's list separator, which makes me suspect that the problem is
in CMake code somewhere.

Looks like you're not the only one to encounter this issue with CMake
on FreeBSD, e.g.:
http://www.luxrender.net/forum/viewtopic.php?f=22&t=2788 .

Common between that instance and rxtools is the use of wxWidgets.  So
I would guess that there's a bug in CMake's FindwxWidgets.cmake,
perhaps specific to FreeBSD and/or the version of CMake you're using.
