Alex Neundorf b01184022b Use absolute path to FindPackageHandleStandardArgs.cmake everywhere
This is to avoid getting an (older) copy of FPHSA.cmake which is
e.g. installed with KDE 4.5.0 and 4.5.1.

# - 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
