body: <p>I try to build the <a href="https://developer.qualcomm.com/develop/mobile-technologies/computer-vision-fastcv" rel="nofollow noreferrer">Qualcomm's FastCV</a> sample fastcorner. I add the project file into Eclipse, and follow the <a href="https://developer.qualcomm.com/develop/mobile-technologies/computer-vision-fastcv/compiling-and-running-fastcv-sample-app" rel="nofollow noreferrer">instruction</a> to "add C/C++ attributes to the project" using "Convert to a C++ Project".

  <p>I try to clean the project, got follow errors:</p>
  
  <pre><code>**** Clean-only build of configuration Default for project FastCVSample ****

  <p>It seems eclipse can not find "awk", but I can successfully execute awk in cygwin, and I also set the C/C++ build envirement variable in "HOST_AWK" in eclipse, nothing helps.</p>
  
  <p>Is there anyone know what should I do?</p>
