Jared,

Because it looks like it's trying to use blocks out of
gnuradio-filter, gnuradio-fft, and gnuradio-blocks, I think you'll
need to link against all of those libraries, too. Using the
GnuradioConfig cmake, you can set all of this up with:

set(GR_REQUIRED_MODULES RUNTIME BLOCKS FILTER FFT)
find_package(Gnuradio 3.7.0)

You'll then have access to the libraries using the following variables:
GNURADIO_RUNTIME_LIBRARIES
GNURADIO_BLOCKS_LIBRARIES
GNURADIO_FILTER_LIBRARIES
GNURADIO_FFT_LIBRARIES

Similarly, you'll have GNURADIO_<package>_INCLUDE_DIRS so you can set
your 'include_directories' in cmake.
