[Discuss-gnuradio] undefined reference error

/home/msi52/src/applications/newpackage/receiver.cpp:-1: error: undefined reference to `gr::bb60c::source::make()'

I am trying to use one of the blocks from an OOT module in another package. But it gives me this undefined reference error on make.

I assume this pertains to linking of the OOT module code. So I have tried adding the OOT module to the find_package in Cmakelists of the new package and created a .pc for it to be found by pkg config module. But still the error remains.

#include <bb60c/source.h>  //header for my OOT module

gr::bb60c::source::sptr     src1;  //the pointer declared in the .h file of my new package. It gives no error

src1=gr::bb60c::source::make(1e9, -20, -1, -1, 2, 18e6, false, false, 0, 0); //the make for the block in .cc file of my package which gives this error

find_package(Gnuradio-bb60c REQUIRED) // find package in the Cmake lists
