I have a suspicion that -DCUTLASS_NVCC_ARCHS='75;80;86;89;90;90a' should be updated — add 120 there.

Interestingly, in Gentoo (https://gitweb.gentoo.org/repo/gentoo.git/tree/dev-libs/cutlass/cutlass-4.2.1.ebuild), this param is set to all-major (which means 75;80;90;100;110;120 according to /usr/share/cmake/Modules/Internal/CMakeCUDAArchitecturesAll.cmake line 14), but that's not very friendly to RTX 3000, 4000, yet friendly to the rare NVIDIA Jetson.

I myself would prefer native (this package takes long to compile), but other CUDA-related packages on AUR don't use native. BTW, there's also all value possible (but that's overkill).

Now pybind11 is missing in makedepends... Also please don't add the nvidia group - there is already an nvidia package in the official repositories, which exists in the same "namespace" as package groups.

Also python-setuptools is missing in makedepends.

The hardcoded -j 48 flag is not nice. You might add ninja to makedepends, -G Ninja to the configure command and remove -j 48 from the build command. Ninja uses all available cores by default.

The build directory can be simply build rather than $pkgname-$pkgver/build.

Also the prefix should not be $pkgdir/usr, the right way to do this is with -DCMAKE_INSTALL_PREFIX=/usr at configure step and DESTDIR="$pkgdir" cmake --install <build_directory> as the install command.
