meson: Add dependency lookups via names used by cmake

 meson: Add dependency lookups via names used by cmake
 
 Particularly on windows it's useful to look up dependencies via cmake, instead
 of pkg-config. Meson supports doing so. Unfortunately the dependency names
 used by various projects often differs between their pkg-config and cmake
 files.
 
 This would look a lot neater if we could rely on meson >= 0.60.0...
