Dear sir

I am trying to catkin_make this package on my own Ubuntu14.04.
But here is something error.

[ 73%] Built target rgbdslam_gencpp
Linking CXX executable /home/ros/catkin_ws/devel/lib/rgbdslam/rgbdslam
/usr/bin/ld: cannot find -lsiftgpu

Invoking "make -j1 -l1" failed

And I find this sentence in README.md,"To build RGBDSLAMv2 go to your catkin workspace and execute "catkin_make". If you get an error about the missing siftgpu library, execute "catkin_make" again."
I don't understand and it doesn't work.

Please give me a hand.
Thank a lot!!

thank you
I edit the camklist.txt and it works.
and if I need sift what should I do to this error?

from rgbdslam_v2.

There's a problem with the CMakeLists.txt, calling the makefile of siftgpu sometimes works and sometimes doesn't. So sometimes just re-runing cmake works. If that fails, you can go to external/SiftGPU and run "make" manually. Afterwards the error should be gone.

I spend quite some time debugging this, but unfortunately I still don't know how to fix this properly.
