Yes, of course

First, I was expecting that kdenlive was a monkey update and I was just fixing bug [1] but we can't build new kdenlive without rttr [2] , searching by that [3]
I feel free to download and add rttr to kdenlive, by patching rttr.CMakeLists.txt with Source1https://github.com/rttrorg/rttr/archive/v0.9.6/rttr-0.9.6.tar.gz + mv ../rttr-0.9.6/ rttr/ + rttr.CMakeLists.patch .

Best regards,

Can you give a little more explanation in the .spec why this is needed?  And document where this rttr tarball comes from please.
