I think it might be more appropriate to pass NO_SYSTEM_ENVIRONMENT_PATH to find_package in case CMAKE_SYSROOT or CMAKE_CROSSCOMPILING are set? That way, we won't search the host system for libxml2 in those cases, but we'll still be able to find it in the custom sysroot or cross-compilation SDK if it's present.
