Thanks, Marcus. I was going to step in and explain this. We spent quite a
bit of time debating the proper use and installation policies of the cmake
modules when we switched to using cmake. Another issue is that of discovery
of the cmake modules. We install ours into $prefix/lib/cmake/gnuradio as
per the Cmake guidelines. However, putting them there meant they were not
necessarily in a place that cmake would discover their existence and you
might have to set some environmental variables to point there. I had tried
a number of different things, but each one seemed to lead us into some
problem or another without a clear and clean solution. We ended up with the
current model because it put the onus on the developers (of GR and the
OOTs) and made it easier for the users.
If we change this behavior, it might be a good target for 3.8. I'm saying
this because we will be updating our dependency versions for 3.8, so we
will need to revisit the cmake modules to make sure they set to look for
the right versions of everything, but it also means a newer version of
CMake, which given all of the work on that project since their 2.6 days
might make this problem a lot easier for us.
