+# The 'REQUIRED' above correctly produces an error for
+# OpenGL and PNG, but there's a bug involving FindGLUT.cmake
+# that fails to produce the error as of CMake 2.8.5.
+# Instead, CMake keeps going and eventually spams
+# the console with a message for every target that used
+# e.g. the ${GLUT_INCLUDE_DIR} variable. So it
+# prints a line for basically every single test in piglit.
+# Work around the bug and error out quickly here instead.
