Because when the package is made the correct permissions are not set.
PackageMaker is a glorified tar utility, thus what ever permissions
are used when the package is create will be used when the installer is
run. For example, if a developer wants his application to be installed
in /Applications then the directory structure /Applications/
MyGreatApp.app/* is created in a temp location then tarred up. What
ever permissions happens to be assigned to that temporary location
will then basically over write the permissions when the installer is
run.
And because you give your admin password when the installer is run
you give permission to the system to change your permissions.
This can probably be taken care of with some more cmake code in the
installation cmake code section.
From the looks of the 'install' command there are no facilities to
actually change the owner:group of a file(s). Maybe that needs to be
implemented. In the mean time a short bash script could probably be
used to fix the owner:group of the generated package _before_ it is
finally packaged up.
Another reason to have a Drag-and-Drop installation for CMake. I
guess someone should file a bug for this.
PS: I speak from experience from years ago when I ran into the same
thing when I was creating OS X installers for my last job and making
some sys admins very unhappy because I was hosing the permissions on
all the OS X systems that installed my app. They all had owner/group
of "mike:wheel" or some such nonsense.

it changes the owner and group of the /Applications folder.
Any idea why? I see the same thing with my own PackageMaker
installers.
