[DEPRECATION WARNING]: Invoking "apt" only once while using a loop via 
squash_actions is deprecated. Instead of using a loop to supply multiple items 
and specifying `name: "{{ item }}"`, please use `name: ['cmake', 'libpng-dev', 
'libtiff-dev', 'liblcms2-dev']` and remove the loop. This feature will be 
removed in version 2.11. Deprecation warnings can be disabled by setting 
deprecation_warnings=False in ansible.cfg.
