Git errors with long file paths on Windows

[dian-nikolov-chaos]

Some of the external library paths become too long if uploaded directly into a git repository and another user tries to check them out locally:

error: unable to create file oidn/external/composable_kernel/library/src/tensor_operation_instance/gpu/gemm_multiply_multiply/device_gemm_multiply_multiply_xdl_f8_f8_bf16/device_gemm_multiply_multiply_xdl_f8_f8_bf16_mk_nk_mn_comp_mfma16x16_kpadding_instance_part1.cpp: Filename too long

A workaround for this is enabling long path support like:

git config core.longpaths true

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled = 1

but if this could be improved in OIDN, it would be nice.

I don't think that this is always the case but only if the path where the repository is checked out is already long.

Unfortunately, we can't do much about this. We could shave off only a couple of characters in OIDN but that still wouldn't solve the problem. Some of our dependencies have such long paths (anything in the external directory), not OIDN.

I would suggest to file a request at https://github.com/ROCm/composable_kernel

If/when the paths will be shortened in the dependencies, we could switch to them in OIDN.
