Look at that same thread for hints on adding the QT5/lib directory to the LD_LIBRARY_PATH environment variable.

I launch Sigil with a custom script that updates the LD_LIBRARY_PATH environment variable beforehand. I use this simple bash script:

#!/bin/sh

# Adds the directory the Qt5 libs are located
# in to the LD_LIBRARY_PATH before launching sigil.

QTLIB_DIR="/location/of/your/Qt5/lib"

if [ -z "$LD_LIBRARY_PATH" ]; then
  LD_LIBRARY_PATH="$QTLIB_DIR"
else
  LD_LIBRARY_PATH="$QTLIB_DIR:$LD_LIBRARY_PATH"
fi

export LD_LIBRARY_PATH

exec sigil "$@"

Obviously change QTLIB_DIR to the location where your QT5 libs are located (and potentially the name/location of the "real" Sigil executable--the one "make install" creates--might need to be modified).

If it all works, I change the real executable (/usr/local/bin) to something like sigil-real and change the custom launch script (also in /usr/local/bin) to sigil so all shortcuts and *.desktop file associations still function as expected.
