[bug#67405] [PATCH] Update fftw3

[Mehmet Tekman]

Hello Mathieu,

I was wondering if you could advise me best on how to handle
this related patch (fftw-cmake):

87o7fmu8or.fsf@gmail.com/">https://patches.guix-patches.cbaines.net/project/guix-patches/patch/87o7fmu8or.fsf@gmail.com/

It's a direct clone of fftw, but built with cmake-build instead of gnu-build.
The reason is that the gnu-build doesn't generate the required *.cmake
files required in a dependent package (krita):

87il5uu5tt.fsf@gmail.com/">https://patches.guix-patches.cbaines.net/project/guix-patches/patch/87il5uu5tt.fsf@gmail.com/

The cmake-build provides all the required *.cmake files for the library, but has
none of the CPU-optimisations in the gnu-build.

Do you know how I can proceed with this? Is it bad etiquette to have a package
that is a direct source clone of another, only built differently?

Best,
Mehmet
