The JavaFX build tools assume WiX is on the system PATH, forcing the developer to download and install this manually and system-wide. This makes it impossible for automated build tools (such as Maven and Gradle plugins) to download WiX for use just by the build. It would be better if the developer could pass in the directory to the WiX executables instead.

The methods affected should be WinMsiBundler.buildMSI and WinMsiBundler.validate.

By default the path should be null meaning the tools should look for WiX on the system path as per normal.
