cmake: disable WITH_GHOST_WAYLAND if any Wayland dependency is missing

This sets WITH_GHOST_WAYLAND to ON and auto-disables it again, if one of
the required Wayland development libraries is missing.

GHOST/X11: enable EGL

This will replace GLX with EGL for X11. GLEW does not support GLX and EGL
at the same time. Most distributions build GLEW with GLX support, so we
have to use the externally provided GLEW and build with EGL support.
This effectively sets WITH_SYSTEM_GLEW to OFF for all Linux configurations.

GHOST/X11: remove duplicated EGL linking

GHOST/X11: don't link GLX when using EGL

GHOST/X11: link libGL for X11-EGL to resolve OpenGL symbols

This links libGL if X11-EGL is enabled, since libOpenGL is not installed by
default on some distributions. This is a workaround to resolve the OpenGL
symbols that would otherwise be resolved via GLVND.

adaptive_cloth: fix: Mesh: collapse edge: can lead to loose edges

There are some edge cases (:P) that can lead to the creation of loose
edges when collapsing the edge.

Suppose v2 has an edge that contains only 1 face and this face also
contains v1, the face was deleted but the remaining edge between v2
and ov, remained. This causes the loose edge. The simple check and
deletion of such an edge fixes this bug.
