# Find the fplutil directory and set it in `FPLUTIL_DIR`.
#
# We search some standard locations, such as
# (1) the variable $(DEPENDENCIES_ROOT), which can be specified
#     in an environment variable,
# (2) the "dependencies" directory that gets created when cloning from GitHub,
# (3) several levels up in the directory tree.
#
# Notes
# -----
# - fplutil is the project where we keep all our shared code, so the code in
#   this file (which locates fplutil) can unfortunately not be shared.
# - Since this file is duplicated in all FPL projects (except fplutil itself),
#   please copy new versions to all FPL projects whenever you make a change.
