Install VTK and integrate it in QT

Installation process

• follow the tutorial explained in this page clone this project from the this gitlab
• use cmake instead of ccmake
• change config in cmake-gui to Release
• after configuring for the first time, remember to change the use qt (or smth similar) form default to YES
• after generating the build files, you need to build the project using the x64 native tools cmd
• After the build is completed, you need to install it using the build system you chose (for integrating and using qtcreator, use ninja)
• re-run the x64 native tools cmd as Admin
• cd to the build folder, then do a ninja install
• At last, create a variable in the Environment setting, called VTK_DIR and point it to the installed location (the defaule in cmake-gui is C:\Program Files (x86)\VTK\lib\cmake\vtk-9.3)
• it’s done!

Integration process

• In order to actually be able to use the vtk in a project, you need to set up the CMakeLists.txt. I can be done inside the QtCreator (under the projects setdxtings) or outside it from the cmake-gui (the same process.)
• In either cases, you need to make the vtk be known to the cmake. You can call the tool by defining a path entry, called VTK_DIR and assign it the value of VTK_DIR variable, defined earlier.
• Then run the cmake. And Enjoy using VTK on Qt Projects!
