Port to Gnuradio >=3.8

[uy0ll]

Hi,
Gnuradio has updated their CMake build files for the upcoming version 3.8:

• Use new syntax for required GR components
• Use gnuradio::gnuradio-* instead of GNURADIO_ALL_LIBRARIES
• Update sources for renamed/consolidated headers

Unfortunately, gr-bruninga does not build anymore with those changes. Can you update build files to fix build against Gnuradio 3.8 ?
