Description:

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems. 1. Non-linear Least Squares problems with bounds constraints. 2. General unconstrained optimization problems. WWW: http://ceres-solver.org/

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

math/ceres-solver: don't force GCC for OpenMP on -CURRENT

Limited to amd64 and i386. LLVM openmp doesn't support other
architectures on FreeBSD (unlike Linux) but it's only important where
Clang is default e.g., aarch64, armv6, armv7.

math/ceres-solver: drop GCC RPATH after r499061

USES=fortran was used to ensure linking against libceres picks up
correct libgcc_s to satisfy dependencies e.g., suitesparse, *blas.

Related to revision 499061 bump ports with USES=fortran to have them
benefit from the improved situation where libgcc_s is only used when
absolutely necessary.

Ports that build out of source now simply can use "USES=cmake"
