Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
Thank you very much Ben for your help,|
I had originally installed CMake 18.104.22.168, however, having read other similar errors reported using this version, I decided to downgrade to Cmake 2.8.7 and reinstall Geant4. At the stage of building opengl & X11 drivers, the errors related to CMP0022 disappeared but the cmake error reading the path to X11_Xmu_INCLUDE_PATH variable not found persisted, until I just found a post on forum (http://hypernews.slac.stanford.edu/HyperNews/geant4/get/installconfig/1484/1.html) and followed the recommendation of installing xorg-dev package (I had previously installed xorg but not xorg-dev) and then the it was built and installed successfully!
