Can't install minio-cpp shared library

I have minio-cpp in my vcpkg.json as a dependency, and every time I try to install dependencies with "vcpkg install --triplet=x64-linux-dynamic", vcpkg install `liminiocpp.a`, not the shared library.
tried adding an option to portfile, but it didn't work
```cmake
OPTIONS
        -DBUILD_SHARED_LIBS=ON
```
