Re: [Discuss-gnuradio] Testers needed: Updated CMake syntax

[Volker Schroer]

Hi,
I tried [1] on Ubuntu 18.10 and it build without problems.
Starting to build some of mine OOT's I found, that FindUSB.cmake is 
missing. I think this was used to build gr-fcd which is not part of 
gnuradio 3.8.
But that's no problem.
Will the new cmake be part of gnuradio-3.8 ?

I'll keep on testing some more OOT's
