Hi Abishek, ah, in that case you'll need to tell your build system to link against GSL. To do that, you will have to add GSL finding ability to your OOT's /CMakeLists.txt and use the found library in lib/CMakeLists.txt. Luckily, gr-wavelet already does this, so you'll basically just have to copy over the things that have to do with GSL from gnuradio/gr-wavelet/CMakeLists.txt to your /CMakeLists.txt and add the libraries to you lib/CMakeLists.txt, just like gnuradio/gr-wavelet/lib/CMakeLists.txt does.
I'm not completely sure, but maybe you'll also have to copy over GNU Radio's FindGSL.cmake from gnuradio/cmake/Modules/ to (you get the idea) to your OOT's cmake/Modules/.
