mbedtls and polarssl first part
polarssl is the old name for mbedtls. Unfortunately the two are confused in eg, Fedora. For our purposes, polarssl or mbedtls < 2.0 has includes in /usr/include/polarssl and polarssl_ apis and we call that "polarssl". polarssl or mbedtls >=2.0 has includes in /usr/include/mbedtls and mbedtls_ apis, we call that "mbedtls". This has to be spelled out clearly because eg Fedora has a package "mbedtls" which is 1.3.x and has the polarssl_ apis and include path. We will deal with that as "polarssl" despite the package name then. This patch lets you use LWS_USE_POLARSSL or LWS_USE_MBEDTLS and set the include and library path like this cmake .. -DLWS_USE_POLARSSL=1 -DLWS_POLARSSL_INCLUDE_DIRS=/usr/include -DLWS_POLARSSL_LIBRARIES=/usr/lib64/libmbedtls.so.9 This patch adds the cmake support and adapts [private-]libwebsockets.h but doesn't modify the apis in ssl[-*].c yet.
