Thanks a lot for your help. Using
 SET_TARGET_PROPERTIES( target PROPERTIES
   RUNTIME_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/bin
 )
does work. However,
 SET_TARGET_PROPERTIES( target PROPERTIES
   RUNTIME_OUTPUT_DIRECTORY_RELWITHDEBINFO
${PROJECT_BINARY_DIR}/bin/relwithdebinfo
 )
still makes an in-source build.

Do you mean like this?
 SET( CMAKE_RUNTIME_OUTPUT_DIRECTORY_RELWITHDEBINFO
${PROJECT_BINARY_DIR}/bin/relwithdebinfo )
I tried that, but that also had no effect.
