The reason seems required libxml2 version is 2.9.10 but in CMaleLists.txt is 2.9.3 then causes some times not re-build (if is found 2.9.3 from other previous build addon).
When used 2.9.3 instead of 2.9.10 causes linker errors.
Tested building locally all pvr.* addons in batch same as Jenkins does.
This addon fails to build in UWP, see: https://jenkins.kodi.tv/view/Windows/job/WIN-UWP-64/17411/
