# Bloom is distributed with some third-party dependencies (in the form of shared objects). These dependencies are

#
# The shared objects are located in bin/lib (relative to Bloom's installation directory). For this reason, we instruct
# the dynamic linker to look for any of Bloom's shared object dependencies in that location first. We do this by
# including '$ORIGIN/lib' in the RPATH of Bloom's binary executable.
