This is intentional.  In general 'libfoo-dev' packages contain header files and symlinks to shared libraries, while ‘libfoo' packages contain the actual shared libraries and other binaries.  Also, in general, the 'libfoo-dev' packages have a dependency on the ‘libfoo' libraries, so they will be installed automatically by apt or dpkg.

In this case, building the ‘libopenvswitch' package involves compiling and linking OpenVswitch code and also some OpenSSL stuff (I believe for TLS), so the header files are necessary.  You’ll get compilation errors without libssl-dev.  You may not notice this if compiling for your host environment, since it may already have the header files in place, but it will quickly become apparent if you try to cross-compile.

regards,
Ben
