Hi,
Which OpenCV version are you using? Can you show the output of cmake? If you don't have OpenCV installed with SURF/SIFT, there is then a problem with the CMake flag telling if OpenCV is built with nonfree module.

Try clearing the cache:

$ cd rtabmap/build
$ rm CMackeCache.txt
$ cmake ..
$ make

cheers
