# On Linux and macOS, set RPATH relative to the origin of the installed
# executables (i.e. relative to the bin directory). This allows us to move the
# installation directory into a different location after installation, which is
# useful e.g. when the installation is performed on one machine but we want to
# run the executables on a different machine.
#
# On Windows, there is no need to set anything as DLLs are installed into the
# bin directory, where they are automatically picked up by executables.
