Add CMake OpenSSL module

[Liryna]

CMake module to detect openssl crystax (based on boost module)

Ok I was too fast on this. I had a corrupt cache during the test and was giving a false positive.
CMake is still unable to find openssl even with correct paths 😢 and I have no idea why...everything seems to be alright 😞

Looks like it is an issue of library name ? Looks like he he expecy to find the library version from the includes in the library name.

Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
  system variable OPENSSL_ROOT_DIR (missing: OPENSSL_LIBRARIES) (found
  version "1.0.2h")

Giving cmake directly the libraries path seems to make cmake happy and build since it override the normal behavior...

cmake -DCMAKE_TOOLCHAIN_FILE=$NDK/cmake/toolchain.cmake -DANDROID_ABI=arm64-v8a -DOPENSSL_CRYPTO_LIBRARY=/crystax-ndk-10.3.2/sources/openssl/1.0.2h/libs/arm64-v8a/libcrypto.so -DOPENSSL_SSL_LIBRARY=/crystax-ndk-10.3.2/sources/openssl/1.0.2h/libs/arm64-v8a/libssl.so ..

I am currently using https://github.com/crystax/android-samples-cmake with crystax nightly
Any idea how to make this more clean 😢 ? I tried everything and I have no other ideas.
