# 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.
