[CMake] CPack source package install location

I'm guessing that CPackConfig.cmake is generated by cmake and not hand written.

CMake generates CPackConfig.cmake that can be used to create a package
with content listed with 'install()' commands (see:
https://cmake.org/cmake/help/v3.5/command/install.html). If those
commands contain header files then those files will be part of the
package. You could also split packages between bin and dev packages by
using COMPONENT attribute in install commands and then generating
component packages - one per component.

This would have to be changed in CMakeLists.txt (install commands) or
is possibly already written with prefix variable in mind in which case
you have to look into CMakeLists.txt install commands and set the
variable that is used there for this purpose.
