With 2.3.1-1, when tworld2 launches, it attempts to load data files, resources and sets from the AUR package directory (e.g. many errors similar to error: /home/brycec/.cache/yay/tile-world/pkg/tile-world/usr/share/tworld/sets/CCLP3.dat-ms.dac: No such file or directory [/home/brycec/.cache/yay/tile-world/src/tworld-2.3.1/fileio.c:115]).

The below patch resolves this by configuring CMake with the appropriate system prefix and then overriding the installation target to be that of the AUR packaging directory.

Edit to add some clarity: tworld2 -d confirms that the default directories are the temporary build directory:

% tworld2 -d
Resource files read from:        /home/brycec/.cache/yay/tile-world/pkg/tile-world/usr/share/tworld/res
Level sets read from:            /home/brycec/.cache/yay/tile-world/pkg/tile-world/usr/share/tworld/sets
Configured data files read from: /home/brycec/.cache/yay/tile-world/pkg/tile-world/usr/share/tworld/data
Solution files saved in:         /home/brycec/.tworld

With the patch:

% tworld2 -d
Resource files read from:        /usr/share/tworld/res
Level sets read from:            /usr/share/tworld/sets
Configured data files read from: /usr/share/tworld/data
