Yes it is, just set CPACK_GENERATOR
with the list of generator you want:

SET(CPACK_GENERATOR "TGZ;RPM;DEB")

would create TGZ, RPM and DEB.
Note however that:
  - some generator suppose you have some tools installed
    which not be available on the host platform.
    e.g. CPackRPM requires "rpmbuild" command
    which may not be installed on a debian-based distro.

  - building an RPM on debian and installing it on
    Fedora may not work (wrong dependencies or library version etc...).
    It's usually safe to build the package
    on the same kind of host you will be installing it.

  - you may have to set the list of Generator depending
    on the Platform (i.e. RPM Generator is not available on Windows)
    something like:
    if(WIN32)
        set(CPACK_GENERATOR "NSIS;ZIP")
    else()
        set(CPACK_GENERATOR "TGZ;RPM;DEB")
    endif()

Nope you can't currently do that:

Currently you may build several package in the same build if you
use COMPONENT installation:
