The "normal" way to have cmake create the correct dependencies is to add the 
files generated through an ADD_CUSTOM_COMMAND() to the list of sources for 
the target (cmake 2.4.3).

But this works only if the target and the custom command are in the same 
CMakeLists.txt (if I understood Brad correctly).
If they are in different directories, the second target which needs the 
generated header needs to depend on a "top-level-target", which itself 
depends on the generated file.

So either:
add_dependencies(kontact_kmailplugin kmailprivate)

(which will also enforce that kmailprivate is built completely before 
kontact_kmailplugin)

or:

in kdepim/kmail/ add a helper target:

add_custom_target(kmail_headers 
                  DEPENDS ${CMAKE_CURRENT_BINARY_DIR}/globalsettings_base.h)

and make the plugin depend on it in kontact/plguins/kmail:

add_dependencies(kontact_kmailplugin kmail_headers)

Then the plugin should really only depend on the generated header(s).
