CMake Depends FAISS 

FAISS is misspelled in the CMake file for CDCPD. This leads to an unnecessary warning message even if FAISS is installed.

Offending code:
```
catkin_package(
        INCLUDE_DIRS include
        LIBRARIES cdcpd
        CATKIN_DEPENDS ${CATKIN_PACKAGES}
        DEPENDS OpenCV Eigen3 GUROBI FIASS Qt5 PCL # NOTE: adding CGAL errors, but it's working so whatever
)
```
