When boost lib is not installed in your system in /usr/include
the set of lib modified by this commite were in default. As they
use xTool xIteratorTools.h they depend on boost header and no
cmake operation give them access to none system boost version. The simple
addition of some Find Boost mechanism covers this prb. Not sure that
it is the best way to solve this issue ... as already said
modern-cmake may be used and in this case give dependency of xtool
to correct boost.
Please in future pay attention to boost dependency. If you add any don't
forget to add find in cmake. Boost are not always installed in
Durty hack to chose the right mkl lib on new c6 Liger install. Should be
completely revisited ....
