Here's one way I've done it.

option(CREATE_MULTI_CONFIG_PACKAGE "Enable creating a multi-config package with 
both debug and release (doubles compile time)" OFF)


if(CREATE_MULTI_CONFIG_PACKAGE)

  set up a secondary build tree at ${CMAKE_BINARY_DIR}/SecondaryBuildTree, 
passing cmake options from here down to the secondary tree to make them match

  I use execute_process to run cmake on the second tree and pass options down 
(which compiler, and project specific settings that the user can modify for the 
primary build tree).

add a custom target to build the second build tree by running "cmake --build"


  # tell cpack to install both projects
  set(CPACK_INSTALL_CMAKE_PROJECTS 
    # self project
      "${CMAKE_BINARY_DIR};${CMAKE_PROJECT_NAME};ALL;/"
    # other config project
      "${CMAKE_BINARY_DIR}/SecondaryBuildTree;${CMAKE_PROJECT_NAME};ALL;/"
      )
endif()
