# Note: This folder is created when Cudd Makefile is executed.
# Because set_target_properties would fail if the file is not present, Cudd is compiled on cmake invocation, and not at build time.
# It is however not possible to build an empty include directory to delay Cudd compilation because Cudd needs this folder not to exist when running make.
