- Don't install CMake or pkgconfig files, or header files.

This fixes PugiXML's location in the Win32 zip file.
pugixml uses "_d" instead of "d".
[pugixml] CMakeLists.txt: Disable options. The cmake_dependent_option()
setup for PUGIXML_USE_POSTFIX prevented the postfix from working because
the top-level source directory is not the same as PugiXML's directory.
[libwin32common] DelayLoadHelper: Handle PugiXML's "_d" postfix.
DelayLoadHelper.cmake has new variables for debug/release only DLLs,
which is used for PugiXML due to the different debug postfix.
