unable to install capybara-webkit in centos 8 - ruby

Question

I'm trying to install capybara, on my ruby 2.7.3 system, and it's failing.
I appear to not be able to look at the output and see the magic words Command 'qmake ' not available
my output:
gem install capybara-webkit
Building native extensions. This could take a while...
