Finish cmake build script for Windows platform

* Matching the build location of examples for all platforms now:
  <build-dir>/<build-type>/examples

* Fix installation of examples -- app, audio -- dependencies (libs & resources)

* Update third-party lib dependency variables to match Ivan's project file

* Disable CPack generator for Windows platform -- no installation support
exists as of this time.
Implement File::path method & fix loading of resource paths with examples
