Hopefully RC2 will be the last one, and that issue is far from being a 
blocker. I've no idea where this shell32.lib or ole32.lib come from as 
they are not referenced in GDAL sources themselves. Presumably from a 
CMake/pkg-config from a GDAL dependency. Perhaps the fix should be in 
that component that appends the .lib. Or maybe not. There's a lot of 
dark magick in cmake/helpers/GdalGenerateConfig.cmake do deal with a 
number of cases. Perhaps a new one is needed to strip out ".lib" 
extension when "-l" is used....? I'm afraid only people with the 
environment that triggers the issue are in a position to come with a 
potential GDAL fix proposal.

Some of them (but perhaps not all) might potentially be considered for 
upstream inclusion. Part of them won't be necessary in master since 
we've started to drop a few of the unused utilities. Up to the people 
annoyed by maintaining them to submit pull requests to GDAL. One per 
topic. Some of the CMake changes (thinking of the PostgreSQL ones) 
should also likely be submitted directly to 
.https://gitlab.kitware.com/cmake/cmake from which a number of the 
FindXXXX.cmake files come from.
