I've never used it but I guess you just have to set the variable
`EXECUTABLE_OUTPUT_PATH' in the CMakeLists.txt at the top of your
hierarchy so that all sub-CMakeLists.txt will inherit this variable.

SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR}/bin)

A full documentation of this variable (and of many others) is available here:
http://www.cmake.org/Wiki/CMake_Useful_Variables

I guess nop. as CMake needs these files. It's not that much anoying as
it's not in your source tree, in few days you won't ever see them ;)
