GTE_IS_SYSTEM_TOOLS_INSTALL is a boolean toggle for controlling what the application assumes about the location of the GTE tool.
If GTE is installed in System:Tools, GTE_IS_SYSTEM_TOOLS_INSTALL must be defined.
Otherwise, GTE_IS_SYSTEM_TOOLS_INSTALL must be undefined.
This will control which header file is used as well as the calls used to load the tool during application startup.
