Hunh, I didn't even know that existed. It's a Qt5 application, it seems 
(unless I've totally borked my ports-tree).

In that case, you should have a cmake-gui.core file, either in you home-
directory, or in the directory where you ran it. Now, signal 6 is ABORT, so 
that usually means something is triggering a software assertion.

No output when you run it from the command-line?

You can use gdb to try to find out what's going wrong:

	gdb  `which cmake-gui`

then at the gdb-prompt, type "run" to run the program without arguments. When 
(if) it crashes, type "bt" at the prompt to get a backtrace.

That, at the very least, should have produced some error messages you could 
put in a pastebin (e.g. https://paste.kde.org/) for others.

One thing to bear in mind is that Qt applications may need to have a DBUS 
session available. If there's no DBUS, they crash with an abort -- you can see 
that happening if you run them from twm on a system without enable_dbus=YES in 
/etc/rc.conf. So it might be that, as well.
