EnLichtIrrnment. B-)
Elementary and Irrlicht don't like to share windows.
Irrlicht can be told to create a device from a pre existing window, but this is Windows only.
Perhaps it already works for Linux, just the docs are out of date?
It works, sorta.
IVideoDriver::getExposedVideoData() can provide a structure with raw OS level window pointers.
This implies that it's theoretically possible to create a device from things other than Windows windows.
Wont provide any valid info when using the software renderer.
Elementary can provide an Ecore_Wl_Window or an Ecore_X_Window of one of it's windows. elm_win_wl_window_get() and elm_win_xwindow_get().
Ecore_evas can provide an Ecore_Window with ecore_evas_window_get().
Ecore_X_Window ecore_x_window_new()
http://irrlicht.sourceforge.net/forum/viewtopic.php?f=2&t=31350&sid=0eb6d64c84ec7043fd48103f8e63e930 may help. A little.
"For using OpenGL with an Evas canvas, there is two possibilities in my
opinion. Either put the canvas in a texture and give it to the 3D
engine, or use EvasGL API and make the 3D engine integrate inside
Evas. It is possible to have a direct rendering path with EvasGL and
so have a fastest possible path.

Apparently Irrlicht's method of providing an external window actually works. Mostly. -

Though seems that bug was marked as a duplicate with the duplicate having a better patch, but NO FUCKING LINK to that duplicate. What a horrid bug tracker.
There is also this which gives clues -http://irrlicht.sourceforge.net/forum/viewtopic.php?f=9&t=26506

http://irrlicht.sourceforge.net/forum/viewtopic.php?f=4&t=46983 where the question I want is not answered.
---------------------------------------------------------
I could run sed over COpenGLDriver.cpp to turn it into CEvasGLDriver.cpp, then tweak it a bit.
evas_gl_make_current(gld->evasgl, gld->sfc, gld->ctx);
glFoo() -> glapi->glFoo()
Hmm, there will be some source files with random gl() calls, and I'd
need to tweak a few other things to suit. So this wont be a clean "just
drop in this source file" patch. B-(
Probably a lot easier to just figure out what what brand of glue to use
to get Irrlicht using Evas created GL surface and context.
