Light OTB superbuild for iota2
The iota2 automatic installation scripts compile OTB using the Superbuild. Many OTB modules and dependencies are not used by iota2. The Superbuild could be configured without all of them. What should be done:
- List the unneeded dependencies and set them to OFF in the cmake configuration step
- List the unneeded OTB modules and investigate how to disable their compilation
