BUG: create modules documentation not only for the first documentation creation step

in cmake (the set ModulesFound wasn't cleared at the beginning of each
PrintDocumentation() function, so when documentation for modules was executed the second
time, ModulesFound already contained all modules and so no module was
documented)
