Be compatible with CMake 3.10 again

[romainguy]

Helps with bug #2295

[bejado]

Can you add the change to the filament-specific-changes.patch file inside the spirv-tools dir?

[romainguy]

Will do!

[romainguy]

@bejado How did you generate that patch file?

[bejado]

The patch file is the output of git diff. You should be able to merge your diff with the current one via:

git diff | tail -n +5 >> third_party/spirv-tools/filament-specific-changes.patch

[romainguy]

@bejado I fixed the patch file

Thanks! LGTM after CI passes
