That doesn't really work, because it makes assumptions as to where the
builddir is, relative to the source dir.

If you want your binaries all put into <builddir>/bin you should use the
EXECUTABLE_OUTPUT_PATH and set it to ${CMAKE_BINARY_DIR}/bin. The same
can be done for LIBRARY_OUTPUT_PATH to have libs in <builddir>/lib.
