"Error while loading shared libraries" after trying to i-use-arch-btw

[consler]

After I run i-use-arch-btw -h I get
i-use-arch-btw: error while loading shared libraries: libiuab.so.0.1: cannot open shared object file: No such file or directory
After I did some research I ran sudo find / -name libiuab.so.0.1 which gave

find: ‘/run/user/1000/doc’: Permission denied
/home/consler/i-use-arch-btw/build/lib/libiuab.so.0.1
/usr/local/lib/libiuab.so.0.1

Which didn`t really give ME any information so I'm asking for help here.

Also a few days ago I reinstalled the OS(arch linux btw)

The dynamic linker/loader is probably not searching for libraries in /usr/local/lib. Try this:

export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/local/lib"
i-use-arch-btw -h

You can also use the i-use-arch-btw-git AUR package which installs into /usr like other packages, so it doesn't require you to change the LD_LIBRARY_PATH environment variable. When you install the project manually with CMake commands, it installs into /usr/local by default.
