Did you list freeglut3 on the commandline when you installed your .deb?
dpkg is the low-level tool for installing packages, it'll barf at you if
you give it a .deb and not all of the dependencies of it are installed
yet and also not listed on the commandline. So either you need to do 

dpkg -i foo.deb freeglut3 <all other dependencies not yet installed> 

or install the dependencies before installing your .deb.

If you want this to work automatically you'll have to look into creating
an APT repository with the corresponding package list and directory
structure. This is something that CMake cannot do for you at the moment.
