warning for failed lens distortion rather than cal failure

when the lens distortions present in the cal images are not well-
suited for the opencv lens distortion model, the calibration fails.
Now a warning gets printed, but the calibration is allowed to proceed.

The lens distortions aren't currently being used anyway. This addresses
issue dicengine#168

address ambiguous namespace issue for VS2017 builds of the tools

also fix one more place where the compiler should not be set
by Trilinos for downstream external projects

output debug images while cal is in progress if requested
