Draft: Link self-compiled VTK version

1. What this MR does / why we need it:

• Compile and link VTK during package creation/installation
• avoid problems with VTK when upgraded by distribution package etc.
• remove unnecessary build-time dependencies (MPI, HDF5 ...)

2. Steps done

• configure script is updated to latest version (used by RcppBTCS etc.) and sets a desired VTK version
• Edited CMake file to pull in VTK source code to desired version and links RcppVTK to necessary VTK targets
• cleanup of source files

3. TODOs

• use compiler flags provided by R
• outsource VTK specific options configure script toCMakeLists.txt

4. Caution

I did not test the functionality of the package at all. So maybe you can give it a quick try @delucia 🙂
