<pre>When I tried to build WebKitGTK+ 2.9.5 from the source tarball today, ENABLE_ACCELERATED_2D_CANVAS gets always set to ON despite of cairo-gl not being available in the system, leading to a build error later on, due to the missing header:
../../Source/WebCore/platform/graphics/cairo/CairoUtilities.cpp:44:22: fatal error: cairo-gl.h: No such file or directory
I've checked this in a 32-bit Debian system, in my Fedora 22 64 bit system, both with the 2.9.5 tarball and the latest code from SVN trunk, and I can reproduce this problem reliably, either using the build-webkit script or cmake.
See the relevant excerpt for a cmake build:
$ cmake -DPORT=GTK -DCMAKE_BUILD_TYPE=Release

Sounds like something is wrong with the CMake rules, because as far as I can tell this feature should only be enable if cairo-gl is actually available</pre>
