title: Main program doesn't reflect wxsmith frame changes anymore in CodeBlocks
body: <p>I'm facing exactly the same situation as in the following thread:
  <a href="https://stackoverflow.com/questions/17521955/editing-codeblocks-wxsmiths-project?answertab=oldest#tab-top">Editing CodeBlocks WxSmiths project</a>.
  I can make changes to mywxframe.wxs but they are not taken into account at compile time. When I rebuild the main program, all the wx widgets remain as if there had been no change. 
  What am I missing?</p>
  
  <p>Thank you in advance for your help.</p>
