find ruby gems & make coverage conditional on BUILD_COVERAGE Summary: new finding tech: - find_gem function configures gem-specific FindFoo files and wraps around find_package - FindFoo files look for ruby and then attempt to require the gem name i.e. it checks if the gem can be successfully loaded by the interpreter - since this is based on find_package it may be influenced in all the regular ways (e.g. forced found or disabled from finding altogether via CMAKE_DISABLE_FIND_PACKAGE_$PKGNAME) various notes for the future: - technically this isn't 100% correct because the require name of a gem and the gem name may not be the same. e.g. the gem `docker-api` has the require name `docker`. for all currently used gems the names are however the same and so simply requiring the gem name is expected to work - the implementation doesn't care about versions, again because we don't need it to - test-unit is a bundled gem, some distributions (e.g. Arch) do split it out without making suitable dependency arrangements on a package level though the tech is heavily inspired by Aleix Pol's tech for finding QML modules as seen in extra-cmake-modules Test Plan: - ruby not found: none of the modules found - test-unit not present: error - simplecov not prseent: never errors - having a module installed or not is reported in the cmake output Reviewers: #dolphin, elvisangelaccio Reviewed By: #dolphin, elvisangelaccio Subscribers: elvisangelaccio, kfm-devel Tags: #dolphin Differential Revision: https://phabricator.kde.org/D19856

Output of licensedigger + manual cleanup afterwards. Unfortunately licensedigger does not strip the trailing * characters. While at it, use a common style for all source files.
