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
