I manufactured a simple setup to demonstrate what I have. I hope this
helps.
Thanks,

I did, then cmake broke the .so down into its component paths and
library name, and used -L<path> -l<libname>, which caused the linker
to look for <path>/lib<libname>.so
It should not do that in 2.6.4, it should use the full path.... Do
you have any policy warnings, or do you have the cmake minimum version
set to something very old?
