Hey Jim,

you're not giving us much to work on here. You might want to specify
what exactly you're linking to, and what you've tried.

What you're trying to do seems like a cmake problem, so checking cmake
tutorials (unrelated to GNU Radio) might help.

Most often, you want your C++ blocks to access some library. This would
mean editing the lib/CMakeLists.txt file to make sure you're linking to
the right libs.
