Description

Currently, the cmake build disable a bunch of interfaces that do not compile on windows CI (c.f. the python PR workflow). This is not a multipers issue per se, but I'll track that here

  • mpfree
  • function_delaunay
  • multi_critical
  • rhomboid_tiling
  • hera

Relevant block of code in cmake/MultipersBuild.cmake:

  if(WIN32)
    target_compile_definitions(
      ${target_name}
      PRIVATE
        MULTIPERS_DISABLE_MPFREE_INTERFACE=1
        MULTIPERS_DISABLE_FUNCTION_DELAUNAY_INTERFACE=1
        MULTIPERS_DISABLE_MULTI_CRITICAL_INTERFACE=1
        MULTIPERS_DISABLE_RHOMBOID_TILING_INTERFACE=1
        MULTIPERS_DISABLE_HERA_INTERFACE=1,
    )
  endif()

I don't have access to a windows machine, so I won't touch that for the moment. Feel free to look at it if you have a windows machine.

Contributor guide

Research direction
Investigate each disabled library (mpfree, function delaunay, multi critical, rhomboid tiling, hera) to identify Windows specific compilation issues. Look for missing header files, incompatible system calls, or dependencies not available on Windows. Check CMake configuration for enabling these libraries on Windows. Consider using alternative libraries or adding conditional compilation with preprocessor directives.
