## Project:	wbuart32, a full featured UART with simulator
##
## Purpose:	To direct the Verilator build of the SoC sources.  The result
##		is C++ code (built by Verilator), that is then built (herein)
##	into a library.
##
## Targets:	The default target, all, builds the target test, which includes
##		the libraries necessary for Verilator testing.
