No variable I am aware of.
However you may create a custom target which call make package and then
move the file, provided you know the name of the generated file ....

The name of the package file is
CPACK_PACKAGE_FILE_NAME+ extension.

If your CMakeLists.txt does not define CPACK_PACKAGE_FILE_NAME
then CPack will define it as:
${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}"

again if CPACK_PACKAGE_NAME is not defined
it is defined by CPack as PROJECT_NAME.
if you want to know more about "default" for unspecified values
I suggest you dive into CPack.cmake file.

Concerning the extension, it is  fixed in the C++ code of the generator
in the GetOutputExtension method:

cmCPackDebGenerator.h:  virtual const char* GetOutputExtension() {
return ".deb"; }
cmCPackGenerator.h:  virtual const char* GetOutputExtension() { return
".cpack"; }
cmCPackNSISGenerator.h:  virtual const char* GetOutputExtension() {
return ".exe"; }
cmCPackOSXX11Generator.h:  virtual const char* GetOutputExtension() {
return ".dmg"; }
cmCPackPackageMakerGenerator.h:  virtual const char*
GetOutputExtension() { return ".dmg"; }
cmCPackRPMGenerator.h:  virtual const char* GetOutputExtension() {
return ".rpm"; }
cmCPackSTGZGenerator.h:  virtual const char* GetOutputExtension() {
return ".sh"; }
cmCPackTarBZip2Generator.h:  virtual const char* GetOutputExtension()
{ return ".tar.bz2"; }
cmCPackTarCompressGenerator.h:  virtual const char*
GetOutputExtension() { return ".tar.Z"; }
cmCPackTGZGenerator.h:  virtual const char* GetOutputExtension() {
return ".tar.gz"; }
cmCPackZIPGenerator.h:  virtual const char* GetOutputExtension() {
return ".zip"; }

+ some other defined in .cxx files.

Note that currently every CPack generator only generates a single file
per project
but it may change depending of the issue of some open bugs:
see for example:

and related bugs.
