Hi,

I am trying the Surface_reconstruction_point_3 demo. All compiling and
linking process are Ok. But when running the executable file, errors occur.
The console messages like these:

### Loading "libPS_demo_average_spacing_plugin.so"...
### Loading "libPS_demo_cleaning_plugin.so"...
### Loading "libPS_demo_inside_out_plugin.so"...
### Loading "libPS_demo_local_spacing_plugin.so"...
### Loading "libPS_demo_normal_estimation_plugin.so"...
### Loading "libPS_demo_off_plugin.so"...
### Loading "libPS_demo_poisson_plugin.so"...
### Loading "libPS_demo_simplification_plugin.so"...
### Loading "libPS_demo_smoothing_plugin.so"...
### Loading "libPS_demo_xyz_plugin.so"...

I am using Ubuntu 10.04 with 32bits CPU. I have followed the suggestion in:
http://cgal-discuss.949826.n4.nabble.com/Re-Error-by-compiling-poisson-reconstruction-example-td2268101i20.html
, in which Laurent said comment the line findpackage(GLEW) in CMakeList.txt
to disable the GlSplat rendering. Although no errors show up, but loaded
data is invisible. So I guess GLEW is necessary in my case. but how can I
address the shader problem?

Thanks a lot.
