%description
Solve optimization problems using an R interface to NLopt. NLopt is a
free/open-source library for nonlinear optimization, providing a common
interface for a number of different free optimization routines available
online as well as original implementations of various other algorithms.
See <https://nlopt.readthedocs.io/en/latest/NLopt_Algorithms/> for more
information on the available algorithms. Building from included sources
requires 'CMake'. On Linux and 'macOS', if a suitable system build of
NLopt (2.7.0 or later) is found, it is used; otherwise, it is built from
included sources via 'CMake'. On Windows, NLopt is obtained through
'rwinlib' for 'R <= 4.1.x' or grabbed from the 'Rtools42 toolchain' for 'R
>= 4.2.0'.
