I’m using the master branch. I wasn’t able to find info on how to do a **complete build** of VTK (that is, excluding modules depending on external libs). After running ccmake iteratively, as explained in the documentation, I thought I had marked everything I needed, but then, I try the GLTFImporter example, and I got
“Skipping GLTFImporter: Could not find the VTK package with the following required components: RenderingContextOpenGL2”
I’m surprised that VTK built without such component, but, anyway, can’t I just tell ccmake to build everything? (everything except for external libs not available) How can I do it?
Thanks!

You can tell VTK to build all modules (that aren’t blocked by options like `VTK_USE_MPI` or whether Python wrapping is available) by setting `VTK_BUILD_ALL_MODULES=ON`. You’ll have to set specific modules to `=NO` if you don’t have the dependencies for them (that information is not known to the top-level selection mechanisms). Off hand, modules which tend to have dependencies:
- Infovis (Boost deps)
- IO (various, particularly IOSQL\*)
- RenderingRayTracing (OSPRay and VisRTX depending on options)
