Compile with sundials>=6

[jschueller]

FMPy does not build with sundials 6.x, here is a small patch to add the necessary context argument when calling sundials functions:
0001-Compile-with-sundials-6.patch.txt
this is necessary to get the full build on conda-forge: https://github.com/conda-forge/fmpy-feedstock/blob/main/recipe/meta.yaml#L46

FMPy does not build with sundials 6.x

Can provide steps to reproduce the problem?

[jschueller]

yes, building from the docker file:

FROM condaforge/miniforge3
MAINTAINER jsr
RUN conda install -y sundials attrs numpy cmake make
RUN conda install -y compilers
WORKDIR /tmp
RUN git clone --depth 1 --recursive https://github.com/CATIA-Systems/FMPy.git
ENV CFLAGS="-I/opt/conda/include/"
RUN cd FMPy && python build_binaries.py

it errors with:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.
