When I want that I do not use Eclipse CDT generator
I use plain Makefile/Ninja generator and configure my own CDT project by hand.
.project/.cproject go into the source tree whereas the generated bits goes
into a separate build dir (usually <src>/build)

The usual way for CMake to deal with that is out-of-source build:
http://www.cmake.org/Wiki/CMake_FAQ#Out-of-source_build_trees
In that case every generated bits goes into "build tree",
this is fine but with Eclipse which does not not support to have
a .project/.cproject outside source if you want to have VCS work.

You can workaround that by setting
ECLIPSE_CDT4_GENERATE_SOURCE_PROJECT to 1.

You can dig the CMake ML about out-of-source build and Eclipse and you'll
see more precisely what I am speaking of.

Separate project for each subdir ? I don't think I get what you want.
