[CMake] Current binary directory confusion

[Robert Dailey]

This is becoming a challenge :-)

I'm generating .RC files using configure_file() in my CMake script. Since I
can have multiple targets defined in the same directory, and the resource
file generated for each target has the same name, I need them to be placed
in the <target_name>.dir directory inside of CMAKE_CURRENT_BINARY_DIR.
Right now I hard-code the path:

set( output_dir "${CMAKE_CURRENT_BINARY_DIR}/${target_name}.dir" )
