If you are not running a dashboard build you can safely ignore this
email. If you are running a VXL dashboard build, let me know if you
have any problem with this.
I just made some changes to the top level VXL CMakeLists.txt file.
There is a new OPTION and all dashboard builds should set
BUILD_FOR_VXL_DASHBOARD:BOOL=3DYES in their CTest script or however it
is done for the original TCL Dart if you are using that. Previously
we were relying on DART_ROOT to indicate we were doing a dashboard
build, but DART_ROOT is not set for ctest builds.
