title: How do I include custom header files in my C++ file in linux?
body: <p>I am new to linux and have some question regarding inclusion of header files. I have created a <code>blinkled.cpp</code> file using nano editor and then I wrote a simple program to blink an LED using BeagleBoneBlack. </p>
  
  <p>For this operation, I specifically configured the GPIO pins such as - exported the pin, set its direction, read/write its value and unexported the pin. Now, I have found a .cpp source file and .h file which has all the GPIO configuration functions.</p>
  
  <p>I have downloaded this from online and at present, the .cpp and .h files are in the downloads directory. I would like to include these files as header in my <code>blinkled.cpp</code> file and use GPIO functions to configure the GPIO pins. So, how do I do this?</p>
  
  <p>Can I just specify the path of the .cpp and .h files to include them in my <code>blinkled.cpp</code> file or there's more to it? Any advice and information regarding this would be helpful.</p>
