# o2_data_file(COPY src DESTINATION dest) is a convenience function to copy and
# install src into dest in a single command. dest should be a relative path.
#
# The install occurs only in the installation phase (if any) and puts src into
# ${CMAKE_INSTALL_DATADIR}/dest
#
# The copy always happens at configure time and puts src into
# ${CMAKE_BINARY_DIR}/stage/{CMAKE_INSTALL_DATADIR}/dest
#
# Note that when src denotes directories src and src/ means different things :
#
# o2_add_file(COPY src/ DESTINATION dest) will copy the _content_ of src into
# dest, while o2_add_file(COPY src DESTINATION dest) will copy the directory src
# into dest.
