Hi,

i was successfully able to build vtk with python wrappings on mac OS using the suggestion given by Dan Lipsa in [using vtk 8.2.0 with python wrappings with anaconda](https://discourse.vtk.org/t/using-vtk-8-2-0-with-python-wrappings-with-anaconda/1060/5), however when i try to follow the same procedure in windows os i am getting the error

 ![error](https://discourse.vtk.org/uploads/default/original/1X/ba7486aee5a4c34f40ff5960a91d8ae11c3fbf1c.png)

basically there is no WrappingPythonCore -8.90.lib in the path

i have set the python path like in the image below and have selected the wrap python option,

even if is set the VTK\_WrappingPythonCore to yes i still get the same error

Can anyone help me with building vtk for windows and anaconda please?

Thanks

hi, sorry for bothering, i was able to fix the issue by setting the LIBPATH environment variable to the directory containing the python libpath

thanks

CMake should be getting the path to the `python36.lib` file and passing it (that first error causes the second error since `vtkWrappingPythonCore` doesn’t get made). Does `python36.lib` show up in `CMakeCache.txt` at all?

hi,  
yes it does, but i think the permission issue was not letting the file to be read during build

`LIBPATH` wouldn’t fix permission errors. I think this is more likely some `#pragma` asking to link `python36.lib` without extra information. Not sure why what CMake is generating with those cache isn’t working here without seeing the link link for `WrappingPythonCore`.
