Note that you have to make sure the icons are available. This is done
in src/Makefile.am by copying them as follows:

if LYX_WIN_RESOURCE
.rc.o:
	cp $(top_srcdir)/development/Win32/packaging/icons/lyx_*32x32.ico .
	$(RC) -I$(top_builddir) --preprocessor "$(CPP) -xc-header -DRC_INVOKED" $< -o $@
endif
