Yes it is. There is this very special file in VTK called vtkIncludeDirectories where alot of the include magic happens. If anything gets turned on or off, every targets include line gets changed causing full recompiles. I have gone in there and removed a few things that I commonly turn on or off such as MPI or Boost but that whole file could use some attention. Also, if CMake supported target level include directories instead of CMakeFile level include directories then things would recompile much less often. <div>
