# NOTE: In order to allow the `TriBITS/` directory to be both a TriBITS
# package (for inclusion in other TriBITS projects) and to be a TriBITS
# project itself, you only have to put in a simple if statement in this
# top-level CMakeLists.txt file.  That is all!  In fact, this `TriBiTS/`
# directory shows how the same directory can be used for a TriBITS package, a
# TriBITS repository, and a TriBITS project!
