hi ,my aim is to debug the program ,so I must add the debug flag -gcflags=all='-N -l' in Makefile or other files, and I added it as below, but it does not works

func buildFlags(env build.Environment) (flags []string) {var ld []string//flags = append(flags, " -gcflags=all='-N -l' ")//new addif env.Commit != "" {ld = append(ld, "-X", "main.gitCommit="+env.Commit)}

how to add the debug flag -gcflags=all='-N -l' in Makefile or other files?thanks .
