The issue isn't just using the cygwin64 include files, it is also using the cygwin64 Python interpreter. If your original C++ library was compiled under cygwin64, then it thinks a C long has 64 bits. I think the cygwin64 compiled Python (and the related include files) also think a C long has 64 bits. So those should all work together.
But the standard Python for Windows thinks a C long has 32 bits and a C long long has 64 bits.
I use "long long" when I need to map a 64-bit integer Python on Windows. This is supported by Visual Studio and mingw64.
I don't know if Cython can resolve the issues of incompatible C compilers.
My recommendation would be to use VS or MSYS2/mingw64 and define your own types so you can use long on Linux and long long on Windows. That should work with either pybind11 or Cython.
