No way to specify PATH variable for qmlpuppet

When loading in the Quick Designer a plugin that depends on a shared library, if the shared library is not in the path when loading the view in the designer, the designer could not load the plugin, and it's impossible to use the plugin with the designer.

The only way is to the the PATH in the system before running QtCreator, or in the Kit. When building project with installed plugins it's not a big issue, but when the plugin and the shared library is build in the same project it is.

It is possible to have a variable in qmake/cmake to specify a PATH for the Quick Designer (qmlpuppet) ? Something like QMLPUPPET_ENV_PATH ?
