Please download and install the GLU drivers/libraries for your
graphics hardware separately, and then set that up as an external
package. An example of a working packages.yaml:
packages:
openglu:
paths:
openglu@1.3: /opt/opengl
buildable: False
In that case, /opt/opengl/ should contain these two folders:
include/GL/ (opengl headers, including "glu.h")
lib (opengl libraries, including "libGLU.so")
On Apple Darwin (OS X, macOS) systems, this package is
normally installed as part of the XCode Command Line Tools in
/usr/X11R6, so a working packages.yaml would be
packages:
openglu:
paths:
openglu@1.3: /usr/X11R6
buildable: False
In that case, /usr/X11R6 should contain
include/GL (GLU headers, including "glu.h")
