1. Setup a target like PRE.% where the % can be matched dynamically.
  2. Then call it using PRE.VALUE e.g. echo.deps.
  3. Use the value in the PRE.% target as $*.

Example:

  • Makefile 
      cyan = "\\033[1\;96m"
  off  = "\\033[0m"

  echo.%:
    @echo "\n$(cyan)Building $*$(off)"

  deps: echo.deps
    pip install --upgrade pip
    pip install -r requirements.txt

  site: echo.site
    rm -rf site
    mkdir site
    mkdocs build
