# Module for locating the Crypto++ encryption library.
#
# Customizable variables:
# CRYPTOPP_ROOT_DIR
# This variable points to the CryptoPP root directory. On Windows the
# library location typically will have to be provided explicitly using the
# -D command-line option. The directory should include the include/cryptopp,
# lib and/or bin sub-directories.
#
# Read-only variables:
# CRYPTOPP_FOUND
# Indicates whether the library has been found.
#
# CRYPTOPP_INCLUDE_DIRS
# Points to the CryptoPP include directory.
#
# CRYPTOPP_LIBRARIES
# Points to the CryptoPP libraries that should be passed to
# target_link_libararies.
