failed build of openrave due to a wrong link flag

Description of problem:
These are two separate but related problems:
1. The pkgconfig file assimp.pc contains /usr/usr/ as prefix for libdir and includedir.
2. The cmake config provides the flag '-lassimpd' instead of '-lassimp', which makes it impossible to link against assimp (there is no libassimpd.so).

Version-Release number of selected component (if applicable):
3.2.0-1

How reproducible:
always

Steps to Reproduce:
pkgconfig: run `pkg-config --libs assimp`
cmake: link against assimp in a cmake project

Actual results:
$ pkg-config --libs assimp
-L/usr//usr/lib64 -lassimp

Linking against libassimp fails with
/usr/bin/ld: cannot find -lassimpd

See attachment for an example.

Expected results:

pkgconfig should return -L/usr/lib64
Linking against assimp should work in a cmake project.

Additional info:
Rawhide is affected, too.
