Android openssl linking

Dear openssl users,

I have an issue on linking libcrypto and libssl.so to my project. I'm using
Android Studio 2.2 and everything about C++ worked properly so far.

I have used the shell scripts in the following link:
https://github.com/stdchpie/android-openssl. 6 for each .so file have been
obtained as arm64-v8a, armeabi, mips, mips64, x86, x86_64. The project
structure is attached with this e-mail. I don't have an Android.mk file but
build.gradle(app). I'm trying to link these libraries, which I think
they're wrong or have missing things, using the part of the gradle script
below:

cmake {
    cppFlags "-std=c++11 -frtti -fexceptions -DWITH_NONAMESPACES -DWITH_OPENSSL"
    cppFlags.add("-I${file("src/main/include")}".toString())
    cppFlags.add("-L${file("src/main/jniLibs")}".toString())
}

The script above is enclosed inside externalNativeBuild which enclosed
inside android.

The error I'm getting is as below:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:externalNativeBuildDebug'.
