But then, you install that FindXXX.cmake file along with the XXXConfig.cmake and in the XXXConfig.cmake file temporarily expand the CMAKE_MODULE_PATH variable before calling find_package (or include() it directly after setting variables such as YYY_FIND_REQUIRED etc).

Agreed, it is not well documented. But then, it is also quite difficult to do so, because what goes into an XXXConfig.cmake file (only import targets, required variabls, or also do version checks, components, ...), whether to use a XXXUse.cmake file etc. varies widely from project to project. And then, if you also want to make this work from the build-directory, you have to got to even greater lengths by using export(TARGETS ...).

If I find the time I probably will start a Wiki page which does the full-fledged thing, but also describes which parts to leave away if a certain feature is not desired/required.
