install it on openSUSE tumbleweed

Trying to install it on openSUSE Tumbleweed and having issues.

I have already the packages installed (see my zypper call in the end of the log) but the gem cannot find it.

Hi @vpereira, you can specify the path to OR-Tools with:

bundle config build.or-tools --with-or-tools-dir=/path/to/or-tools
bundle install

or

gem install or-tools -- --with-or-tools-dir=/path/to/or-tools

(no need to clone the project and run rake compile)
