Improve linking of test/cairo_test.cxx demo program
With modern CMake libcairo doesn't need to linked explicitly in the test/cairo_test.cxx demo program. Either '-lcairo' is implied by linking with fltk::fltk or it is not used at all. This fixes a linker warning on macOS: "ld: warning: ignoring duplicate libraries ..."
