[CMake] ctest submit through proxy environment settings

[Wheeler, Frederick W (GE, Research)]

I've solved a minor problem for myself.  I want to report it here in case it will help anyone else in the future.

I could not get ctest 2.0.6 to submit for the VXL project through an http proxy using the HTTP_PROXY* environment variables.  What finally worked for me was unsetting the HTTP_PROXY* environment variables and setting:

  http_proxy=proxy.company.com:8080
  export http_proxy
  ftp_proxy=proxy.company.com:8080
  export ftp_proxy

Setting ftp_proxy seems to be enough to get the files uploaded.  Setting http_proxy allowed the submit to trigger the dashboard as well.  Even with http_proxy and ftp_proxy set correctly, I needed to unset the HTTP_PROXY* environment variables to get the submit to work.
