When I call find_package(XercesC REQUIRED) and XercesC is not in a standard

I use to rely on a custom FindXercesC.cmake file that was using XercesC_ROOT to
figure all this out.
Is there any way to do the same here?
There seem to be no Xxx_ROOT_DIR handled by this module

No, but CMAKE_PREFIX_PATH should be sufficient. We can certainly add
XercesC_ROOT, but is it really needed? Matthieu, did you try
CMAKE_PREFIX_PATH at all?
(I'm not sure what the CMake policy is on this point. Is
CMAKE_PREFIX_PATH support alone sufficient for Find modules?)
If the consensus is that Find modules should all provide ROOT_DIR type
variables, then I'm sure patches to FindXercesC and FindXalanC would be
appreciated.
