Adding Library per file in QSYS component _hw.tcl file

The same problem here.. VGopa7's original question seems to concern naming an analysis labrary for VHDL files. When one of analyzed VHDL files defines a package, and rest of the files refer to that package using a library name, e.g.

library mylib1;

use mylib1.pkgname.xxx;

compilation will fail if Platform Designer / Quartus has analyzed these files to some other compilation library than mylib1. In Component instantiation tab, under Compilation Info, there is a selection for HDL compilation library. However it did not have any effect when I tried it. Also there is an attribute HDL_COMPILATION_LIBRARY but how to use it, is it for this purpose?
