Re: [Discuss-gnuradio] Problem/bug with cmake config for gr-uhd using pybombs.

[Martin Braun]

Eugene,

I've seen something similar, and I'm not even sure it's a PyBOMBS
problem. I think it's more likely an issue with gr-uhd's (or even GNU
Radio's) CMake.

Not sure what the fix is though. I'll post an issue.

Cheers,
M
