title: turn off warning in leksah
body: <p>For a good reason, I want to temporally turn of the warnings about the missing type level signature in the leksah IDE.</p>
  
  <p>I changed the flags to ghc cabal file and the warnings are absent when I run "cabal install" from the console. </p>
  
  <p>However, if I build the same project in the leksah IDE, the warnings are still shown.</p>
  
  <p>How can I turn off  "Warning: Top-level binding with no type signature:" in the leksah IDE?</p>
