[Bf-committers] Blender 2.5 OpenCollada doesn't import animation?

[Erwin Coumans]

Right now, the Blender trunk doesn't compile out-of-the box with OpenCollada
enabled using cmake, because

1) OPTION(WITH_OPENCOLLADA "Enable OpenCollada Support (
http://www.opencollada.org/)" OFF)
(that is easily fixed, and I assume it is because things are still
work-in-progress)

2) the include path and library path are not correctly set

It would be good that if OPENCOLLADA is not defined, it should use
lib/<platform> from the Blender SVN repository.

For example OPENCOLLADA should point to lib/<platform>/opencollada/include

Library include path is set to \usr\local\opencollada for Windows, it should
use lib/<platform>/opencollada/lib

3) why does one platform (Mac/Apple) use OPENCOLLADA_INC and all the others
OPENCOLLADA?

I haven't had time for a patch yet, but is someone (Arystan or someone
else) looking into this?
Thanks,
Erwin
