# This file performs the bridge between the CMake configuration and the Lit
# configuration files by setting up the LitConfig object and various Lit
# substitutions from CMake variables.
#
# Individual configuration files can take advantage of this bridge by
# loading the file and then setting up the remaining Lit substitutions.
