+# We support different versions of SSL:
+# - "bundled" uses source code in <source dir>/extra/wolfssl
+# - "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.
