# 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. | |
