If you want to have control over what is installed the better to do that
is to create COMPONENT.

> This is a part of my CMakeLists.txt:
>
> install(TARGETS ${PROJECT_NAME}
>           DESTINATION "Demos"
>           COMPONENT ${PROJECT_NAME})

like this but I doubt that you can name a COMPONENT with the same
name as the name of your project.

then you must either define:
set(CPACK_INSTALL_CMAKE_PROJECTS
"${CMAKE_CURRENT_BINARY_DIR};${PROJECT_NAME};${PROJECT_NAME}:/")

see documentation
cpack --help-variable CPACK_INSTALL_CMAKE_PROJECTS

> set(CPACK_PACKAGE_NAME "${PROJECT_NAME}")
> set(CPACK_PACKAGE_VENDOR "Me")
> set(CPACK_PACKAGE_DESCRIPTION_SUMMARY "Example test framework: demos
> ${PROJECT_NAME}")
> set(CPACK_PACKAGE_VERSION_MAJOR "1")
> set(CPACK_PACKAGE_VERSION_MINOR "0")

By the does your Demo/ directory have a "project(...)" command in its
CMakeLists.txt?
