[Paraview] EGL build of ParaView

[Alexandre Ancel]

Hello Dan,

Regarding to the values of the variables, I have:

//No help, variable specified on the command line.
EGL_INCLUDE_DIR:UNINITIALIZED=/data/software/install/EGL/include

//Path to a library.
EGL_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libEGL.so

//No help, variable specified on the command line.
EGL_gldispatch_LIBRARY:UNINITIALIZED=/usr/lib/x86_64-linux-gnu/libGLdispatch.so.0

//Path to a library.
EGL_opengl_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libOpenGL.so

The libraries are OK (They come from the manual installation of the Nvidia
driver which should be at least 355 if I remember well). I have a 358.16.

I didn't previously saw that EGL_INCLUDE_DIR was marked as UNINITIALIZED,
however ParaView was built successfully with the previously mentioned
options.

I am just not sure about the libGLdispatch.so.0 library, as it is not a
symlink to a libGLdispatch.so.358.16.
When I do a "strings libGLdispatch.so.0", I have gl*NV functions, so I
guess it should be ok.

As I said before, remote rendering is working but only when I add
"--disable-xdisplay-test" to the pvserver.

Regards,

Alexandre Ancel
