Summary

Add GSL to OTB Superbuild. It will allow to package CESBIO's remote modules (TemporalGapFilling, PhenOTB and otb-bv).

Rationale

To facilitate cross-platform compilation and configuration in the superbuild, for now I use a fork of GSL which CMake build support: https://github.com/ampl/gsl

I found the link to this fork on gnu.org: https://www.gnu.org/software/gsl/extras/native_win_builds.html

Implementation details

GSL added as an external project in the superbuild.

Moreover the TemporalGapFilling remote module was added in the OTB package.
