If you build your project with CMake, and you use the standard find_package(VTK) and include(${VTK_USE_FILE}) then this problem should not occur. (Because the defines will be automatically added for you by virtue of the include(${VTK_USE_FILE})...) Consider following the guide to using implementation modules, which has fuller details on using implementation modules without using CMake if your project demands it.
