<div>Thanks for your replying. You provide a way to add "-g" flags to all source files. However, I only want to compile the source files in "pt2pt" with additional "-g" flag. Other source files are expected to be compiled with original CFLAGS. I know this requirement is strange, but it is exactly what I want.</div>
