-Subject: [PATCH] - Apply mechanism to decide use for IrrXML external or
- internal
-
-Several distributions usually decide for shared external libraries
-instead of an usual embedded, for security reasons, duplicatiion issues.
-This change enable the possibility to set SYSTEM_IRRXML=ON for detect
-and build against a system installed irrxml.
-By default, the internal copy is compiled.
-
-Changes on build:
- Added a FindIrrXML cmake module.
- Moved the source recipe for proper CMakeLists inside contrib directory
- Includes aren't path based anymore, using the provided INCLUDE_DIR
- Compiler option are grouped in a singled entry on main CMakeLists

-Subject: [PATCH] Enable doxygen been properly used from cmake build and
- install.
-
-Current documentation lacks a proper directory handling and switch for
-Unix like systems.
-The option BUILD_DOCS are added as disable by default, even so the
-Doxyfile file is generated for a manual build.
-
-Option HTML_OUTPUT are made cached to be properly replaced, as usually
-done by some Linux distributions
-
-Microsoft CHM option is enabled if MSVC is detected.
