In general OpenSG does try to load animations from collada files,
however, it is possible that some tweaks are required in order to
support the way a specific tool represents animations in a collada file.
IIRC, the information should be stored in an attachment on the root node
of a scene. You can take a look at
Examples/Advanced/Character/character.cpp:initAnimationsEnterFunc, which
uses OGRE files, but should otherwise be quite similar.

Hmm, I don't think SimpleShadowMapEngine requires additional libs and if
it did I'd expect it to crash rather than produce wrong images without
those libs. Black (blocky) artefacts are sometimes a sign of incorrect
bounding boxes (since these are used to find the projection needed to
render the scene from the light source's point-of-view). If bounding
boxes on the cluster nodes are correct it might be helpful to run the
nodes under an OpenGL debugger in order to look at the shadow map
textures generated by the SSME.
