Description Dennis Klein 2017-09-06 12:24:38 CEST 
Dear Geant4 team,

when integrating Geant4 via its Geant4Config.cmake into our project, it sets the CMAKE_CXX_EXTENSIONS option to OFF. This is a global cmake option and should in my opinion not be set by an included dependency. I propose to prefix the variable with Geant4_ as done with all the other variables. So, the user can decide whether to apply this setting.

Best regards,
Dennis

Apologies for the delay in this. We're looking at this in relation to a larger review of compiler flags required (rather than recommended) for use when compiling/linking Geant4 libraries.

This is now fixed on master, so will be in the next 10.6 release, plus patches.
