Hi!
I just installed CentOS 7 on my Rpi4 and wanted to try hatari there, but for some strange reason cmake doesnt like libreadline very much there.
-- Looking for pthread_create in pthread - found

Libraries summary :
-------------------
- sdl : using SDL2 v2.0.10
- readline : not found, install it to enable debugger history/completion
....
Well... why? :-) It's there.
I can even force it by adding "#define HAVE_LIBREADLINE 1" in config.h and it compiles just fine.
