#  - remove make/optdepends on adios2, openimagedenoise, ospray
#  - add makedepend on tbb, previously pulled in by ospray
#  - add makedepend on nlohmann-json, previously pulled in by adios2
#  - explicitly disable the fides, adios2 modules due to -DVTK_BUILD_ALL_MODULES=ON
#  - generalize moving .so files in install
#  - removed -ffat-lto-objects from CFLAGS
