RFC: COMP: use relative includes for VTK and ITK (!870) · Merge requests · Sam Horvath / Slicer · GitLab

Isaiah requested to merge github/fork/ihnorton/vtkitk_relative_includes into master Jan 17, 2018

Opening for discussion, ref https://discourse.slicer.org/t/duplicated-includes/1862

script: https://gist.github.com/ihnorton/b9d0a18b3ae00bb5fb78b143eda79d70
how to spot-check (in slicer source dir "s5"):

:s5 $ cat `find ./ -name *.cxx -or -name *.h` | egrep "#include.*itk" | less
:s5 $ cat `find ./ -name *.cxx -or -name *.h` | egrep "#include.*vtk" | less

Build system TODO
- Teach build system to clone {vtk,itk} in e.g. SuperBuild/VTKv9/vtk
- Teach build system to pass single include path for vtk as e.g. SuperBuild/VTKv9/
- ? Fix bundling cmakescript ?
