What is your platform/build tool?
Windows/ Visual Studio?
Linux / Makefiles?

Which CPack generator are you using?

Do you modify the CPACK_PACKAGE_NAME value
**before**

include(CPack)

?

It should work, unless you use a "multi-config" capable IDE like Visual Studio.

In this case and if you want to support more "dynamic" things you could use
a CPACK_PROJECT_CONFIG_FILE as described here:
http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#Overall_usage_.28common_to_all_generators.29

> send Debug or Release as an option to cpack (e.g. cpack -C Debug)?

I missed that in the first place.
You NEED to use CPACK_PROJECT_CONFIG_FILE if you want to change
some CPACK_xxx values  at CPack time.

The variable set in CMakeLists.txt are evaluated **at CMake time**
cpack won't always re-run CMake if launched with "cpack -C Debug".
