Create config for debug builds

[pktiuk]

Allow simple creation of debug builds in cmake.

These builds should have:

• disabled optimalization
• enabled printing stacktrace in case of segfault link link2
• (maybe) simple way of creating stack traces

I think this will help with #159

Moreover in regular builds reporting filename and linenumber doesn't work

[15:54:44.277] 🟢INFO "Quitting Program" (file main.cpp:737)
[15:54:44.278] 🐞DEBUG  Display have local data (file x11extras.cpp:84)
[15:54:44.279] 🐞DEBUG  removing main window (file mainwindow.cpp:214)
[15:54:44.291] 🐞DEBUG  Closing logger (file logger.cpp:54)

vs

[12:54:41.542] 🐞DEBUG	Display have local data (file :0)
[12:54:41.543] 🐞DEBUG	removing main window (file :0)
[12:54:41.547] 🐞DEBUG	Closing logger (file :0)
