bugfix [#24518] Blender wont compile with -Wall -Werror and COLLADA support

fix included in report from Martijn Berger (mberger)
made some small changes.

- use ints rather then unsigned long for printing, values are not likely to be very large.
- CMake remove strict flags from collada build dir since I had warnings in the collada headers.
- added xml2 to collada libraries else I couldnt get collada building.
