# We support different versions of SSL:
# - "bundled" uses source code in <source dir>/extra/yassl
# - "system" (typically) uses headers/libraries in /usr/lib and /usr/lib64
# - a custom installation of openssl can be used like this
# - cmake -DCMAKE_PREFIX_PATH=</path/to/custom/openssl> -DWITH_SSL="system"
# or
# - cmake -DWITH_SSL=</path/to/custom/openssl>
#
# The default value for WITH_SSL is "bundled"
# set in cmake/build_configurations/feature_set.cmake
#
# For custom build/install of openssl, see the accompanying README and
# INSTALL* files. When building with gcc, you must build the shared libraries
# (in addition to the static ones):
# ./config --prefix=</path/to/custom/openssl> --shared; make; make install
# On some platforms (mac) you need to choose 32/64 bit architecture.
# Build/Install of openssl on windows is slightly different: you need to run
# perl and nmake. You might also need to
# 'set path=</path/to/custom/openssl>\bin;%PATH%
# in order to find the .dll files at runtime.
