# CMake configuration file for folly

# This provides the Folly::folly target, which you can depend on by adding it
# to your target_link_libraries().
#
# It also defines the following variables, although using these directly is not
# necessary if you use the Folly::folly target instead.
#  FOLLY_INCLUDE_DIR
#  FOLLY_LIBRARIES

####### Any changes to this file will be overwritten by the next CMake run ####
####### The input file was folly-config.cmake.in                            ########
