This patch is a dependency of krita 5.2.1, and is a clone of the fftw
gnu-build which does not provide a required CMake file for krita.

It is not clear if the CMake build provides the target optimizations, so
it does replace the existing fftw variable.

Subject: [PATCH] gnu: Add fftw-cmake

* gnu/packages/algebra.scm (fftw-cmake): New variable

  This is a clone of the fftw function, but uses cmake to build in order for
  the FFTW3LibraryDepends.cmake file to be built, neccesary for packages with
  cmake builds that depend on fftw3.

  See: https://bugzilla.redhat.com/show_bug.cgi?id=1729652#c5

  This variable is cloned from the existing fftw3 in order to not break any
  downstream packages that make use of the target optimizations given by the
  gnu build.
