0.17.6 install fails

[johnpitchko]

Hello, updating my gems for a Jekyll site and it seems this gem is now required. Unfortunately, its install fails (because cmake is not installed?). This is my first experience with this gem, so really not sure what it is or what it does. My Jekyll site/gems built fine previously; all I did was add jekyll-livereload gem.

I will install cmake via homebrew and try bundle update again. Will let you know what happens.

Error log below:

Did brew install cmake fix it for you? It ought to, according to #47.

[johnpitchko]

Hello, yes sure did! So all is good in the universe!

May I suggest, as a way to help future newbs like me, that a note be added to the README that make is required? And how to install it using Homebrew? Happy to make the PR if you wish.

@johnpitchko Glad to hear it! We're currently working on a PR to make cmake not required at all; #60 is in progress.

0.17.7 is now released which removes this dependency. Thank you very much for your report!

[johnpitchko]

You're welcome @kivikakk have a lovely Friday.
