GLUT_LIBRARIES not set on Ubuntu 12.04 x64

I get this output from configure:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
GLUT_LIBRARIES
    linked by target "001_triangle" in directory /home/david/git/oglplus/example/oglplus
    linked by target "002_rect" in directory /home/david/git/oglplus/example/oglplus

plus a whole bunch of other target references for the examples.  I do have freeglut3 installed, and "g++ -lglut" finds it.  I did a bit of poking around and couldn't identify the root problem, so I just commented 'add_subdirectory("example")' in the cmake script.

-no-examples didn't seem to do the trick, and it looks like OGLPLUS_NO_EXAMPLES isn't actually hooked up to anything.  I didn't really look into it too much, so I thought I would post here rather than putting in a bug.

P.S.  I'm just about to start on my first full-on C++11 project using opengl, and I'm looking forward to using oglplus.

Thanks for reporting this. I'm going to open a new bug report in the tracker and look into it.

OK, I've made some changes to GLUT detection.
Could you pull from the repo and try now;

I cannot reproduce the problem on any of my machines
so if the update does not help, could you please put some message()s
into ./config/FindGLUT.cmake and find out what is going on?

How is the GLUT_LIBRARIES variable set after the calls to
1) include(FindGLUT)
2) find_library
3) and before and after the loop through the values in TMP_GLUT_LIBRARIES

thanks

I noticed you added a bug for this, so I posted some info and a patch on it.

I'm impressed with oglplus so far.  I even installed g++ 4.7 to take advantage of all features.  It's a great showcase for C++11.
