Allow kissfft to be imported as an External dependency (!10905) · Merge requests · VTK / VTK

Paul Harris requested to merge paulharris/vtk:vtk-kissfft-external-module into master Feb 21, 2024

I'm not sure why kissfft cannot be compiled externally and used with VTK, as with most/all of the other 3rd party libraries.

This patch fixes that.

Note that a header file needed a patch due to a change in file location between VTK's version and the upstream version: VTK has vtkkisfft/tools/kiss_fftr.h Upstream has include/kissfft/kiss_fftr.h (I'm using the external package from conan)
