# OR_ROOT is the minimal prefix to define the root of or-tools, if we

# contains the trailing separator if not empty.

# INC_DIR is like OR_ROOT, but with a default of '.' instead of
# empty.  It is used for instance in include directives (-I.).

# OR_ROOT_FULL is always the complete path to or-tools. It is useful
