brew install openssl?

@misi I have tried brew and source compile both to install openssl

I faced the same problem then as per the instructions given in https://github.com/coturn/coturn/blob/master/INSTALL file, I download the openssl pakage from openssl.org and follow the other steps.

        1) Download the OpenSSL version from openssl.org.
    2) Let's assume that we want to install the "custom" OpenSSL into /opt.
    Configure and build OpenSSL as:
        $ ./config --prefix=/opt
        $ make
        $ make install
    Those commands will install OpenSSL into /opt, with static libraries (no 
    dynamic libraries).
    3) Build the TURN server:
        $ ./configure --prefix=/opt
        $ make
    Those commands will build the TURN server binaries, statically linked 
    against the newer OpenSSL.

It worked well.

When you install openssl via Homebrew you get this warning.

This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

So you need to explicitly point the compiler to the library. The following worked for me.

$ export LDFLAGS=-L/usr/local/opt/openssl/lib
$ export CPPFLAGS=-I/usr/local/opt/openssl/include
$ ./configure
$ make

The same as above works for me..
See travis file:

It think this issue has now resolved, so I am going to close it. Please comment or open new if you still has issue with it.
