CGAL complains about missing QGLWidget

[boegel]

Hi there,

while building target CGAL-4.0-goalf-1.1.0-no-OFED-Python-2.7.3.eb
I came across an error mentioning missing "QGLWidget", as per
http://www.cgal.org/Manual/latest/doc_html/installation_manual/Chapter_installation_manual.html#Subsection_4.13

On debian squeeze I resolved it by bringing libqglviewer-qt4-2, libqglviewer-qt4-dev and their deps;
for RedHat and its offsprings you might wish to call your "dag" neighbour for more info:
http://rpmfind.net//linux/RPM/dag/redhat/el5/i386/libqglviewer-2.2.3-1.el5.rf.i386.html
(a quick search in an SL5 with default repos did not reveal the answer to this)

cheers,
Fotis

Seems like we have these deps installed on our end, which explains why we missed this:

-bash-3.2$ locate QGLWidget
/usr/lib64/qt4/include/QtOpenGL/QGLWidget
/usr/lib64/qt45/include/QtOpenGL/QGLWidget
-bash-3.2$ rpm -q --whatprovides /usr/lib64/qt4/include/QtOpenGL/QGLWidget
qt4-devel-4.2.1-1.el5_7.1

So, we'll need to see if we can add support to EasyBuild build/install qt4.

For now, we'll add qt4-devel as os dependency for CGAL, which at least makes this issue clearer.

pull request to be reviewed, real fix (supporting qt4 in EasyBuild) will have to wait for now

I'm going ahead and merging this simple pull request. I want develop to be complete, so I can run a full regression test before making any more major changes (e.g. renaming functions).
