As I already tried to explain the last time when you asked
essentially the same question: Because the WITH_OPENGL passed to
AM_CONDITIONAL is a string (An m4 string autoconf uses to compose its
internals), and no shell
variable.

You have set up a *shell*-variable named WITH_OPENGL if you want to
AC_SUBST it. 

For example something similar to this should work.
...
WITH_GL=yes
...
AM_CONDITIONAL(WITH_GL,test -n "$WITH_GL")
AC_SUBST(WITH_GL)
