If I want to generate document files as part of the build, should I first
create an ADD_CUSTOM_TARGET then have it depends on the generated files
defined by ADD_CUSTOM_COMMAND? ( It would be nice if file generation can be
defined as a target so the extra step is not needed. )

Do the targets always run by the order that they are defined in CMakeLists
(unless there are dependency) ? So that if I want to be sure a target is run
before all others, I define it first in CMakeLists?

Thank you,
