Thanks for prompt response! The real reason for inclusion of those "external" sources is the size of our projects.
We have read-only "shared/public" workarea were all the sources reside. The developer checks-out only the files that should be modified during his current task (his source files are complemented with "public" files during the build). We try to avoid copying/duplication of a large number of files to developer's workarea (which takes time/bandwidth, requires frequent updates and raises chances for inconsistency). With the same rational we'd like to avoid copying of sources to ${CMAKE_BINARY_DIR}.

Apart from me not liking this setup (those external sources should probably be a separate project and be compiled as a library which then is imported) you could use CONFIGURE_FILE(/long/path/to/file ${CMAKE_BINARY_DIR}/file COPYONLY) and then pass ${CMAKE_BINARY_DIR}/file to the add_executable/ add_library calls. You could also wrap the latter commands in custom macros/functions to scan a list of source files for out-of-source sources and the automatically copy them to the build tree. Michael On 30.
