cmake: Check dependencies for Linux Qt package

Currently Qt will download whether or not the target system supports the
package. Normally this isn't an issue since the package manager would
work out the dependencies for us, but in this case we must make sure
everything is in place before downloading the package.

This checks for the package's requirements, as well as tries to provides
hints as to what is required on some of the more cryptic dependencies.
