This undoes most of the Xerces related part of the commits listed below.
The issue resolved here is that the Xerces include dir *is* set in the
CMakeLists.txt of src/Base, but it got removed from various App and Gui
dirs in src/Mod. If those now include a header from src/Base, which
itself includes xercesc, the build fails using Apple clang version 11.0.0
(clang-1100.0.33.17) on Mojave, configured using cmake 3.22.1, with
errors like the following:
In file included from .../src/Mod/Part/App/FeaturePartBoolean.cpp:34:

The FCGlobal.h can be included in a Global.h header file of an extension module.
The reason is that some IDEs (e.g. QtCreator) fails to detect the export/import macros when only defined in the PreCompiled.h files and thus raise a parser warning.
