> Currently building with custom rdma-core installed in /opt/rdma-core after
> setting PKG_CONFIG_PATH=/opt/rdma-core/lib64/pkgconfig/ results in the below
> meson logs:
> Run-time dependency libmana found: YES 1.0.54.0 Header
> "infiniband/manadv.h" has symbol "manadv_set_context_attr" : NO
> 
> Thus to fix this, the libs is updated in meson.build and is passed to the
> cc.has_header_symbol call using dependencies. After this change, the libmana
> header files are getting included and net/mana is successfully enabled.
