18
# - "system"  (typically) uses headers/libraries in /usr/lib and /usr/lib64
 
19
# - a custom installation of openssl can be used like this

#     - cmake -DCMAKE_PREFIX_PATH=</path/to/custom/openssl> -DWITH_SSL="system"

# For custom build/install of openssl, see the accompanying README and

# On some platforms (mac) you need to choose 32/64 bit architecture.
 
32
# Build/Install of openssl on windows is slightly different: you need to run
 
33
# perl and nmake. You might also need to
 
34
#   'set path=</path/to/custom/openssl>\bin;%PATH%
