After removing libnl3-devel I get (from cmake)

-- The following OPTIONAL packages have not been found:

 * NL
 * PORTAUDIO
 * YAPP

-- Configuring done
-- Generating done
-- Build files have been written to: /home/osboxes/wireshark/build

But I have libnl-devel. That sounds a bit confusing to me... Which lib is cmake looking for? Libnl or libnl3? 

Anyway, without libnl3-devel compilation goes to the end.

I' trying to compile the current master on Centos7. Some of the code in caputils doesn't compile, so I patched it. Now the compilation stops with

I'm using cmake and this is the list of libnl(s) installed

Compilation in-tree with autotools works fine.
Any idea?
