# Try to find the OpenSSL encryption library

# Once done this will define

|
|
# OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL
|

# Read-Only variables:
|
|
#
|
|
# ::
|
|
#
|
|
# OPENSSL_FOUND - system has the OpenSSL library
|
|
# OPENSSL_INCLUDE_DIR - the OpenSSL include directory
|
|
# OPENSSL_LIBRARIES - The libraries needed to use OpenSSL
|
|
# OPENSSL_VERSION - This is set to $major.$minor.$revision$path (eg. 0.9.8s)
