title: how to add libraries to a make file
body: <p>I'm editing an example file already in a library.  Inside the directory of the example, there is a Makefile that I have been using to compile and run the example.  I now want to add an additional library to this make file, I have tried copy and pasting the header and .c file into the library folder specified in the Makefile, but it is not finding it. Here is the Makefile code:</p>
  
  <pre><code>CPPFLAGS = -I../../include
  CFLAGS = 
  LDFLAGS = -L../../lib -L../../lib64
  LIBS = -lbsapi
  
  Biometry: main.c
      $(CC) $(CPPFLAGS) $(CFLAGS) $(LDFLAGS) main.c -o Biometry $(LIBS)
  </code></pre>
  
  <p>The library that I wanted to add came with a .h file and a .c file.  I have added those to the ../../include directory and made sure to add this to my code right below the previous #include</p>
  
  <pre><code>#include &lt;tpl.h&gt;
  </code></pre>
  
  <p>I am not sure what I am missing? The program ran properly before the addition of this library.</p>
