Ok. I might help in the future if you point me on a specific line and 
explain me the mistake.

It might help if you send me the test log file of the run. On the other 
hand, I do not understand why it would be an error if "${dpkg_depends}" 
is an empty string. (I should still be able to find from an empty 
string, shouldn't I?)

I won't be able to install a Debian box any time soon. The test tests 
the following setup:
- automatic dependency discovery on by default 
(CPACK_DEBIAN_PACKAGE_SHLIBDEPS)
- global/default dependency set (CPACK_DEBIAN_PACKAGE_DEPENDS)
In this case, I do not want the component APPLICATION to inherit from 
the general dependency, but rather let the shlibdeps tool do the work.
This is why I do the following:
set(CPACK_DEBIAN_APPLICATIONS_PACKAGE_DEPENDS "")

In this case, the component dependency is set, which prevents inheriting 
from CPACK_DEBIAN_PACKAGE_DEPENDS, and only the result of shlibdeps go 
to the package.

Best,
