Pass variables on command line

More make commands

• Run parallel jobs
  make -j4 testcopy

  Run up to 4 recipe lines in parallel

• List all targets (with help pattern)
  grep -E '^[a-zA-Z_-]+:.*?##' Makefile | awk -F':.*##' '{printf "%-20s %s\n", $1, $2}'copy

  Convention: annotate targets with ## comments for self-documenting Makefiles

• Force rebuild ignoring timestamps
  make -B buildcopy

  Unconditionally remake all targets (-B / --always-make)

• Specify Makefile path
  make -f infra/Makefile plancopy

  Use a Makefile in a different directory or with a different name

• Phony targets declaration
  .PHONY: build test deploy cleancopy

  Prevent make from confusing targets with files of the same name
