03 / ORIGINAL ISSUE TEXT

PointCloudLibrary/pcl #1173 · read the original issue

When compiling pcl 1.7.2 on archlinux without glu installed, I get a compilation error that `GL/glu.h` can not be found.  I realise this can be fixed easily by installing glu but it seems to me that cmake should have errored out before compilation even started or disabled whatever features depend on glu.

As far as I can tell, the cmake files look for opengl and optionally glut, but not glu.

```
/build/pcl/src/pcl-pcl-1.7.2/apps/point_cloud_editor/src/cloudEditorWidget.cpp:51:21: fatal error: GL/glu.h: No such file or directory
 # include <GL/glu.h>
```
