OpenSSL forces c++_shared – why?

**Describe the bug**
If I use prefab for openssl, it can only be linked with c++_shared, but this library is pure C, isn't it?

**To Reproduce**
Steps to reproduce the behavior:
1. open a new JNI project
2. change the C++ file to C
3. add openssl dependency as prefab

**Expected behavior**
The project should build without STL

**Build system:**
CMake
