make CppunitTest_sw_layoutwriter CPPUNITTRACE=TRUE # which is a shortcut for the following line
make CppunitTest_sw_layoutwriter CPPUNITTRACE="'C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/Common7/IDE/devenv.exe' /debugexe" # for interactive debugging in Visual Studio
make CppunitTest_sw_layoutwriter CPPUNITTRACE="drmemory -free_max_frames 20" # for memory checking (install Dr.Memory first, and put it to your PATH)
