The LCLWidgetType is an IDE macro. The package lcl has some conditionals
to add unit paths and for some widgettypes linker options.
If you want to compile a lcl app without Lazarus/lazbuild and without
passing command line options, then you could add unit paths to the
source. You loose comfort - you have been warned.
