After running CPack with the WIX generator you will have a 
"_CPack_Packages\<arch>\WIX" directory.
Within are all the WIX sources and everything else used to build the 
installer.

In "files.wxs" you can find all the component definitions and their IDs.
Here you can also find your patch fragments (if they are being 
successfully applied).

Using a non existent ID in a patch file should generate an error at 
CPack time.

If you are currently successfully generating an installer with an 
invalid ID that might indicate that the patch file isn't being used at all.
Is it possible that you are using an older CMake release or that you are 
setting CPACK_WIX_PATCH_FILE after or outside the context of your 
include(CPack)?

CPack only sees the options that make it to CPackConfig.cmake which is 
generated by include(CPack).
