[CMake] Preferred way to find Qt5 Plugins with CMake 3.x

[Michael Jackson]

I am trying to locate specific plugins from the Qt5 installation. I guess in previous iterations of FindQt4 possibly the "QT_PLUGINS_DIR" may have been defined because I am using this variable in my Qt4 based codes. I am still trying to wade my way through Qt5 so I maybe missing something obvious on how to do this. Any help is much appreciated.

Thanks
