You could use the SUPPORT_FLAC/* variables to add -D flags when
compiling the examples.  See the add_definitions command in CMake.

If you were to do that, name it something else to keep it distinct from
ALLEGRO_HAVE_<foo>, which is defined if some third party "foo" was
detected at configure time, whether or not the user wants to make use of
it.

We also have ALLEGRO_CFG_* constants, but those are internal and users
should not be encouraged to use them.
