Source: vtk9 Version: 9.3.0+dfsg1-2 Severity: wishlist
Dear Maintainer,vtk9 source has embedded exprtk.hpp which is now provided by a package of its own, libexprtk-dev. Moreover, libvtk9-dev installs the embedded header. Please consider unembedding exprtk.hpp and build-depending on libexprtk-dev instead. FYI, I have not checked whether your package builds with exprtk.hpp from libexprtk-dev.
