Subject: [PATCH] xml2cpp: Add missing EXPAT include dirs (#136)

This patch is required if EXPAT library is installed in non-standard location.
Without 'target_include_directories' cmake will find EXPAT library:
  ...
  -- Found EXPAT: .../lib/libexpat.a (found version "2.2.10")
  ...

But 'xml.cpp' compilation will fail with error:
  ...
  tools/xml2cpp-codegen/xml.cpp:7:10: fatal error: expat.h: No such file or directory
    7 | #include <expat.h>
  ...
