librsync-rs Windows support?

Trying to compile the basic example from the docs on Windows, fails in liner. Not sure if it's specifics of my Windows configuration, or whether this crate doesn't have Windows support yet. The original librsync should build normally on Windows.

The crate compiles normally on Mac OS with correct delta files generation. On Linux (Ubuntu server) I noticed different file size generated for a delta patch. And on Windows cannot build yet.

librsync/src/checksum.c(28): error C2491: 'RS_MD4_SUM_LENGTH': definition of dllimport data not allowed
librsync/src/checksum.c(29): error C2491: 'RS_BLAKE2_SUM_LENGTH': definition of dllimport data not allowed

Yeah, I fear this was broken with the last updates. The problem is that I no longer have access to a Windows machine, so I can't easily check Windows support.

Could you follow the steps in https://github.com/mbrt/librsync-rs/blob/master/librsync-sys/README.md and see whether you get different generated headers for Windows?

  --- stderr
  CMake Deprecation Warning at CMakeLists.txt:20 (cmake_minimum_required):
    Compatibility with CMake < 2.8.12 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.


  CMake Warning (dev) at C:/Program Files/CMake/share/cmake-3.21/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
    The package name passed to `find_package_handle_standard_args` (LIBB2) does
    not match the name of the calling package (libb2).  This can lead to
    problems in calling code that expects `find_package` result variables
    (e.g., `_FOUND`) to follow a certain pattern.
  Call Stack (most recent call first):
    cmake/Findlibb2.cmake:12 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
    CMakeLists.txt:177 (find_package)
  This warning is for project developers.  Use -Wno-dev to suppress it.
