Option for building without a network connection #12

Closed schornakj closed 4 years ago

schornakj commented 4 years ago

Currently tesseract_ext checks for updated versions of Bullet and the other external projects every time I build my workspace. This is rather inconvenient when I'm making experimental changes directly on my robot, since it isn't always possible to get a wired internet connection e.g. if the robot is deployed offsite.

Is it possible to configure the Cmake ExternalProject_Add function to gracefully continue with the currently-downloaded version of the package in question if a network connection isn't available?

I would update to leverage UPDATE_DISCONNECTED option. It would be good to create a cmake variable for this option which defaults to true, but it would allow user to change it when building if the upstream has changed and they want it to check.
