How to install VTK linux

[Gresliebear]

you want to follow these steps https://gitlab.kitware.com/vtk/vtk/blob/master/Documentation/dev/build.md

git clone --recursive https://gitlab.kitware.com/vtk/vtk.git

in the terminal
sudo apt install build-essential
sudo apt install cmake
sudo apt install mesa-common-dev
sudo apt install mesa-utils
sudo apt install freeglut3-dev

after install the dependencies, we are going build VTK from source

mkdir -p vtk/build
cd vtk/build
cmake ../ -DBUILD_SHARED_LIBS=ON -DBUILD_TESTING=ON -DCMAKE_BUILD_TYPE=Release -DVTK_WRAP_PYTHON=ON

These ' -DVTK_WRAP_PYTHON=ON` allow pyvista to work or vtk python package

then build the source
make -j4
it will take long time hour or more

then flask run in the correct directory where the app.py i.e. wsgi.py or run.py
`flask run --host=0.0.0.0'

Go to your public IP address see if the server is showing up
