No rule to make target libcmark_static

[louisch]

On Windows 10, trying to install commonmarker with gem install commonmarker, I get this:

libcmark is missing.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib

extconf failed, exit code 1

The mkmf.log file says the following:

Thanks for the extensive report. I'm on vacation at the moment but I'll check this out when I am able.
