This updates Krita from 5.1.5 to 5.2.1, with extra package dependencies
from:
- [bug#67342] Add kfkdcraw : https://patches.guix-patches.cbaines.net/project/guix-patches/patch/87r0kiu8u5.fsf@gmail.com/
- [bug#67343] Add fftw-cmake : https://patches.guix-patches.cbaines.net/project/guix-patches/patch/87o7fmu8or.fsf@gmail.com/
Please apply these patches first before testing this patch.
The fftw-cmake patch aims to address some missing FFTW Cmake files,
during the Krita configure stage, but sadly it still does not find them.
I'm submitting this patch in the hopes that someone can help debug this
issue further. I've CC'd the mentors teams.
Below is the current state of the patch.

Disregard the last patch, the one below is the complete patch which
successfully builds the package.
It depends only on fftw-cmake (#67343) and kfkdcraw (#67342) to be
merged first.

Subject: [PATCH] gnu: krita: Update to 5.2.1
* gnu/packages/kde.scm (krita): Update to 5.2.1
Due to a missing patch in the upstream libraqm, we cannot depend on
the existing libraqm library, but must instead use the one embedded
in the package. It compiles, but needs to be told to use the -fPIC
flag.
Dependency fftw also does not provide the required CMake file
FFTW3Librarydepends.cmake, and only does so when compile via cmake
and not gnu. Due to the many packages that depend on fftw, a
seperate fftw-cmake was used.

This is a hotfix that should be applied ontop of the previous patch.
For some reason I thought that kfkdcraw did not exist already in Guix,
but upon closer inspection I see that it does indeed exist under the
name "libkdcraw".
