DirectX_LIBRARY was always clearing, though DirectX_PREFIX_PATH was not changed. This is because I had some semicolons at begin of DirectX_PREFIX_PATH and the macro `clear_if_changed` discarded them. Now it saves all extra semicolons and check passes.
This fixes the following warning:
The package name passed to `find_package_handle_standard_args` (rt) does not match the name of the calling package (RT).
By default, Linux distro installs assimp into /usr/include/assimp

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
Note: Current internal assimp irrXML is older than upstream irrlicht 1.8.4.
To enable usage of this version, code need to be patched.
The GTest framework has a more active support base, and natively
supports CMake. Introduce it as an external dependency (using CMake's
ExternalProject_Add), replacing cppunit and porting the associated unit
tests.
