OK, so at least it isn't total "pie in the sky" thinking on my part.

I guess this is going to end up being a judgement call based on
cost/benefit.

If 98% of builds do not use CMAKE_INSTALL_PREFIX then taking a while to
satisfy the 2% could be seen as lacking in sufficient benefit. My gut
reaction though is that if it isn't masses of effort, then covering
this 2% case is likely to have sufficient "it all works out of the box"
positive vibes to be worth it.

I'll see if I can do some research on this over the weekend. No
promises though, it is a Six Nations weekend.
