I would guess at some point you go to move to MSVC2012... 2014...  and have the
option to use CMake's project files or to create your own, at that point it may
be easy just to use the generated ones.

Is there a list of build environments you support? or do you just mean IDE/OS
configuration?

Sounds good.

Ill check on this when I get some free time (weekends probably).

As for output, its common for cmake projects not to do (or allow) in-source
builds, so developers create their own build dir and that references the source
path. makes it very convenient to debug/release intel/clang/gcc... etc compilers
all pointing to the same build.

At first this seemed annoying to me but now I much prefer it since you dont mix
up build files in your source dir.

If others have a strong opinion in-source builds can be supported, but this
isn't really that big of a deal and can be changed later.

Only curious if there is anything thats nonstandard going on or any code
generation.
