We've been through this on the thread earlier when it was "CONFIG_HELPER".
The information contained in the variables is about the PACKAGE, not about
the HELPER.  It is PACKAGE_INCLUDE_INSTALL_DIR because the include dir
is for the PACKAGE.  Even the _INIT variable contains code that computes
information about the PACKAGe.  There is precedent for this in the
find_package command's interface for package version files.
