[CMake] CMake/CPack /w BundleUtilities on Windows with NSIS fails

[Bill Somerville]

Hi,

I have a CMake script that runs on Windows with MinGW Makefiles that 
builds the install target OK. It is a Qt GUI application and uses 
BundleUtilities::fixup_bundle to pull in and link/rpath prerequisites.

When I build the package target with an NSIS packager it looks like the 
fixup_bundle stage breaks in some way. I get several of the following 
message box pop up in the install phase.

---------------------------
link.exe - System Error
---------------------------
The program can't start because mspdb80.dll is missing from your 
computer. Try reinstalling the program to fix this problem.
---------------------------
OK
---------------------------

If I dismiss them all the build finishes without error but none of the 
prerequisite libraries or Qt plugins are in the install kit (they go in 
/w the install target as expected).

I suspect a PATH problem but have no idea how to debug this further.

TIA
Bill.
