There is a typo in that help.  It has the word "toi"

Ok, I'm running into that probably of not finding dependencies within my own 
package.  In the package, there are some 3rd party plugins without rpaths 
(these plugins don't need them), but it complains about not finding dependent 
libraries.
Do you know if there is some what to give it the path?

I'm hoping for something like this in my cpack config (which doesn't work):
set(ENV{LD_LIBRARY_PATH} "$ENV{DESTDIR}/${CMAKE_INSTALL_PREFIX}/lib")

I'm curious why rpmbuild didn't have this problem, do you know?

And why would automatic dependencies be ON by default for RPM but not for DEB?
