Hi guys, I’m trying to build a vtk-8.1.2 package for python.  
I need to run a software that requires this version of vtk, I was able to install it using pip on Intel architecture, but now I need to run it on my ARM computer.  
I’m building using the sequence of commands listed below:

```
wget https://www.vtk.org/files/release/8.1/VTK-8.1.2.tar.gz
wget https://www.vtk.org/files/release/8.1/VTKLargeData-8.1.2.tar.gz

mkdir VTK-8.1.2/build/
cd VTK-8.1.2/build/

cmake -DCMAKE_INSTALL_PREFIX=/home/public/app/firedrake_arm/vtk \
      -DCMAKE_INSTALL_RPATH=/home/public/app/firedrake_arm/vtk/lib \
      -DPYTHON_EXECUTABLE=/opt/spack/opt/spack/linux-centos7-thunderx2/gcc-9.2.0/python-3.6.8-fucqk4xf5x2tlargbkis56jowbhcia3f/bin/python \
      -DPYTHON_INCLUDE_DIR=/opt/spack/opt/spack/linux-centos7-thunderx2/gcc-9.2.0/python-3.6.8-fucqk4xf5x2tlargbkis56jowbhcia3f/include/python3.6m \
      -DPYTHON_LIBRARY=/opt/spack/opt/spack/linux-centos7-thunderx2/gcc-9.2.0/python-3.6.8-fucqk4xf5x2tlargbkis56jowbhcia3f/lib/libpython3.6m.so \
      -DVTK_WRAP_PYTHON=ON \
      -DVTK_PYTHON_VERSION=3 \
      -DVTK_WHEEL_BUILD=ON \
      ../

make -j 64
make install

```

It works, I can compile without errors, but my software search for the file “vtkCommonKitPython.so” and this file isn’t in my vtk directory.  
So, how can I compile vtk in order to create this file? In whl files from pip the file vtkCommonKitPython.so is created.

Thanks,  
Luis
