Sebastian Parborg be83b8f456 Cleanup: CMake warnings related to "find package" modules
Fix package name missmatch in a few module files. IE "ALEMBIC" was
defined in the file but the find_package commands used "Alembic"

Some modules state that they set and use the _LIBRARY variable but the
do in fact not do this. Removed these comments from those files.
