Hi Tom,

I started with a clean build directory and after cmake finishes
without errors I get:

address@hidden ~/sdr/gnuradio/v3.6.3-146-ga54dc5ba/build $ cat
CMakeCache.txt | grep ENABLE_BAD_BOOST
ENABLE_BAD_BOOST:BOOL=OFF
address@hidden ~/sdr/gnuradio/v3.6.3-146-ga54dc5ba/build $ cat
CMakeCache.txt | grep "Boost_VERSION"
Boost_VERSION:INTERNAL=104601
