I just tried your example in VS 2005 and it seemed to work.  When I 
built release
it said it could not find dbgtest.lib:

 1>------ Build started: Project: blubblub, Configuration: Release Win32 
------

But if I build Debug:  it fails to find dbgtestd.lib.

$ less blub.deps
SET(blubblub_LIB_DEPENDS "dbgtest;dbgtestd;")
SET(dbgtest_LINK_TYPE "optimized")
SET(dbgtestd_LINK_TYPE "debug")

library_LINK_TYPE is looked up before a library is output.

So, the example seems to be working ok...
