"libicui18n.so.60: cannot open shared object file: No such file or directory" on Linux

Users have reported the following error on Mint and Solus distributions:

error while loading shared libraries: libicui18n.so.60: cannot open shared object file: No such file or directory

I saw a similar issue with another Qt application a while back:

Upon installing a newer version of libicui18n.so.60, one user gets another error:

./Slate: error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory

According to the comments in AIIX/Mycroft-Ai-QtApplication#4, one of solving this is to bundle libicui18n and libpng with the app. I'm not using linuxdeployqt though, and I'm building statically...

I've been told that the easiest way to fix this is indeed to ship the ICU libs with the app. This will require wrapping Slate in a shell script which sets LD_LIBRARY_PATH beforehand.

It seems that I can actually run a dynamically-built Slate deployed with linuxdeployqt without problems now, so I think I'll try that instead, as it will allow me to use pre-built binaries in the future:

As a bonus side effect of this, it seems that linuxdeployqt correctly deploys the ICU libraries, so that patch should fix this.

The newest released fixed this problem for me, thank you! 👍

Good to hear! Thanks for the feedback!
