Qt Creator cmake project paths

[Poldi]

I have a cmake project that is identical over two different version of Qt Creator and am trying to figure out why one of the crashes.

Following are the System settings

I think the problem is that the ApplicationsLocation on the second environment misses the "/home/llist/kdedev" path.

How do I add this path to a cmake project?
Thanks

Are running this on two different computers (or VMs)? It seems there are more variables involved than just 'different version of QtCreator'.

Working:

Qt 5.12.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 8.3.0) on "xcb"
OS: Ubuntu 19.04 [linux version 5.0.0-38-generic]

Environment:
QT_ACCESSIBILITY="1"
QT_AUTO_SCREEN_SCALE_FACTOR="0"

Not Working (note, QT_ACCESSIBILITY is not set):

Qt 5.12.4 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 9.2.1 20191008) on "xcb"
OS: Ubuntu 19.10 [linux version 5.3.0-40-generic]

Environment:
QT_AUTO_SCREEN_SCALE_FACTOR="0"

Do you have additional KDE packages (not sure what that the 'kdedev' folder is) installed on the one that's working? Does your application depend on them? Can you run it in debugging to see where exactly it is crashing?
