In case my problem is related to a missing VTK module, I decided to try to build all modules (instead of just those related to Qt.) This gives me a cmake error:
CMake Error at C:/Program Files/CMake/share/cmake-3.30/Modules/FindPackageHandleStandardArgs.cmake:233 (message):
Could NOT find Boost (missing: Boost_INCLUDE_DIR)
To install Boost, do I need to build it from source?
On a different line of attack: I have been choosing to build Module_GuiSupportQt, but not Module_GUISupportQtOpenGL. Is it possible that I need to include the latter module in the build (if I do not build all module, which I currently can’t do, lacking Boost.)
