Title: cmake: Allow to compile with system breakpad.

The patch for Google Breakpad only seems to be needed when building for Windows, so I guess we can safely allow to use breakpad from the system.

This commit depends on b262dff51214439f8713523f94a92b82ae602e30 from pull request #265, as it contains `$(REQUIRED_IF_OPTION)`, as we don't want to force non Windows users to actually have breakpad available (do we? :smile:).
