[CMake] Why does CMake 3.9.0 open VS2017 when targeting 2013 after installing 2017... sigh.

This is an article about side-by-side toolsets
https://blogs.msdn.microsoft.com/vcblog/2017/11/15/side-by-side-minor-version-msvc-toolsets-in-visual-studio-2017/
but it looks like it only goes back to 2015...

(and sorry to ramble a bit)
Slightly off topic; but I ran into a feature of the new optimizer that
shuffles commands.... I had a critical section lock that it ended up
clearing the locking bit, before releasing the other value; can defiantly
see lots of code breaking from that; firefox wants to only build with 15.6
but community is only 15.5 or 15.8 preview...  (I fixed the codea dding
'volatile , and referencing the other value with a computation that
resulted with 0 instead.)

Sometimes code is in a certain order for specific reasons :) Sometims, it
can be shuffled ....   (a=1;b=2;) ~~ (b=2;a=1) (same result different order)
