Certainly checking for $ENV{DISPLAY} is trivial; that leaves the GLU
check. Is there a reliable place to find libGLU? Is it guaranteed to
be in /usr/lib ? What is the correct capitalization under cygwin? For
that matter, is the cygwin libGLU a .so or a .dll?
In other words, is the following a sufficient check?
$using_x11_mesa = defined $ENV{DISPLAY}
&& -e '/usr/lib/libGLU.so';
Hmmm. Will the cygwin libGLU work without using X11? (Do we have to
check for $ENV{DISPLAY} there?)
What do we do if the user has both libGLU and glu32 installed?
