From Roland Smeenk, "Attached are two small fixes:

-I changed the SET of COLLADA_BOOST_INCLUDE_DIR to use findpath, so users may override this setting if they choose not to build against to precompiled boost libraries delivered with the Collada DOM.

-Changed daeRMaterials.cpp to prevent a compiler warning about a potentially uninitialized variable."
