-# 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.
