Either set CMAKE_RUNTIME_OUTPUT_DIRECTORY or the target property RUNTIME_OUTPUT_DIRECTORY to e.g. ${CMAKE_BINARY_DIR}/bin. This will cause all the files that are required during runtime to be created in the specified directory. For other kinds of files, there are similarly-named variables and properties.
