A file is a file, and you have to specify the relative or full path to 
that file.  A target is something
that is being built by cmake, and cmake will know what it is where to 
find it, and how to install
it.

Right now, everything in your source tree gets packaged in 
package_source.  You can exclude
files with regular expressions.   The cpack source packages do not use 
the install commands
at all.  They just package up all the files in your source tree.
