Minimum cmake version is fixed (thanks @ceres-c). Those still having issues with cmake minimum version - delete cached version of the PKGBUILD from your device and try again. As this change does not affect package itself. pkgrel was not changed, so your AUR helper may not download updated version of the PKGBUILD by itself.

PKGBUILD patch for the updated cmake version

Hi, this is harmonization with wiki cmake template https://wiki.archlinux.org/title/CMake_package_guidelines#Template and fix for systems where the default cmake build system is something else than GNU make (e.g.: ninja)

Building this version (r799.fe86885-3) doesn't update the pkgver/pkgrel but installs it as the old version (r799.fe86885ecaf-1), resulting in the package reappearing again and again as available update.

A quick fix to this is to delete the entire pkgver () function in the PKGBUILD (line 22 - 25).

@xyproto Thanks, both are now fixed :)

This patch was needed in order to build ffts-git on Arch Linux ARM (without SSE2):

https://github.com/anthonix/ffts/pull/78

The dependency on cmake seems to be missing.

@kbeckmann done!

It would be nice if this package built a shared library as well. Could you please add -DENABLE_SHARED=ON to the cmake arguments?
