support SSL when embed build libgit2

[alexband]

before we use embed builded libgit2 & a fork of pygit2 in our environment

as #354 introduces credential , it needs libgit2 version which build with SSL support

this the same problem described here: libgit2/rugged#260

I'm trying to fix this in my environment and I would like to get some help how to build an embedded version of libgit2 with SSL support to pair with my pygit2 upgrade

How is it the same issue? We don't provide statically-built versions. pygit2 supporting credentials does not mean you need a version of libgit2 built with OpenSSL support (if it does that's a bug in libgit2).

As for building a static version of libgit2, you pass -DBUILD_SHARED_LIBS=OFF -DCMAKE_C_FLAGS=-fPIC to CMake when configuring it. You then need to make _pygit2.so contain that code and link that to libgit2's dependencies. See rugged and git2go for examples of how to get that form pkg-config.

@carlosmn maybe because we use the embed version make -f Makefile.embed

now I managed to to follow the CMAKE from rugged example and then make _pygit2.so with -Lssl and -Lcrypto seems fix my problem

so I closed the issue

thanks
