Are you setting CMAKE_<...> variables before creating you targets of after
that?

Also, try to output the values for the CMAKE_<...> flags and of the
COMPILE_OPTIONS property of each target (i.e. "message ("CMAKE_<...>
${CMAKE_<...>}")") to see where the flags appear first. You may try to
perform experiments, e.g. create a target without setting any CMAKE_<...>
variables and output its properties, set CMAKE_<...> variables and then
create a target and output its properties, etc. This way you will understand
the consequences of different actions.
