IMPORTANT! nokogiri-xmlsec1 builds and uses a packaged version of #{name}.

If this is a concern for you and you want to use the system library
instead, abort this installation process and reinstall nokogiri-xmlsec1
as follows:

    gem install nokogiri-xmlsec1 -- --use-system-libraries

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri-xmlsec1 --use-system-libraries
