title: Getting a string input with make command to use as a main argument in C program
body: <p>I'm having trouble using makefile commands to get a user input. What I need is to ask the user the name of TXT file (which is located in ./data/), then to use the path to this file as an argument for my main C program.</p>
  
  <p>Make code :</p>
  
  <pre><code>launch-app-conway: app-conway
    @read -p "Enter file name: " FILENAME
    FILEPATH = "./data/"
    FILEPATH += FILENAME
    ./main-program FILEPATH
  </code></pre>
  
  <p>It outputs "FILEPATH : command not found".</p>
  
  <p>Thanks for the help ! </p>
