Re: [Discuss-gnuradio] gr-lte make error

Hi all,

I'm uncertain how to integrate VOLK into the 'gr-lte' CMakeLists file.
I've just looked at some other modules. I ended up just adding the line
'find_package(Volk)'. This ends up in a 'works for me'. CMake finds
'VOLK' and I could just compile 'gr-lte' from a new github clone.
Though, I can't find a line where the library or include dir are
actually added to the corresponding lists.
Also, it seems like there is no 'findVOLK.cmake' file in 'cmake/modules'
(not only in gr-lte. It's also missing in other OOT modules). Could
someone point me in the right direction where I can find some more infos
on this whole 'find_package' CMake magic?
So far I've pushed my change to a new branch 'cmake-volk-fix'.
