# On Windows we need to correctly export global constants that are not inlined with the use of GenerateExportHeader

# To ensure that the build works even if find_package(VTK) is invoked and VTK 6 is found, we manually include exactly the
# GenerateExportHeader that is shipped with CMake, extracting the CMake install prefix from the CMAKE_COMMAND variable
# This workaround can be removed once we will not support anymore platforms that ship with vtk 6.3 as main vtk version (Ubuntu 18.04).
