If you look closer at my script you'll find out that this line above is
the problem. You may not need to know the boost version on your system
because boost/version.hpp is installed in /usr/include, however thats
not the case on all systems.

And reading out the version string from version.hpp can be done without
compiling a program (as can be seen in my FindBoost.cmake). The problem
is finding version.hpp and finding the right version of it.
