Help with rear derailure

Hi,
I’m trying to put a R8000 groupset on to a BMC SLR01 2011 frameset
I’ve got to the rear derailure but am now struggling. The derailure won’t slide onto the hanger as there isn’t enough gap and there isn’t going to be anywhere near enough range to hit the last sprocket.
I tried a 10 speed Tiagra I had lying around which fit perfectly but obviously couldn’t quite hit the upper and lower sprockets.
Do I need an older 6800 derailure or is there another way?
The cable routing on the R8000 looks to come out of the front as opposed to the rear which my bike is setup for is this a problem too?

    No idea what this means. 'Slide' onto the hanger? What 'gap'? Range is defined by the limit screws. Can you explain again?

    I’ve figured it out. I bought a secondhand groupset, they have not included the hanger part on the derailure. I’ve never seen a derailure like this before so assumed it slotted into the bike hanger.
    I’ll have to source the hanging part of the derailure
