Hi!
While working on the "reproducible builds" effort [1], we have noticed
that ossim could not be built reproducibly.
The attached patch removes extra timestamps from the build system:
* avoid_overwrite_build_date.patch: avoid overwrite OSSIM_BUILD_DATE
through TODAYS_DATE in CMakeLists.txt if OSSIM_BUILD_DATE was already
defined.
* debian-rules.patch: modify debian/rules to set the variable
OSSIM_BUILD_DATE in cmake command line.
Once applied, ossim can be built reproducibly in our current experimental
framework.
