In Geant4InterfaceOptions.cmake the line (around line 218): find_library(X11_Xmu_LIBRARY Xmu ${X11_SEARCH_PATH}) Should be: find_library(X11_Xmu_LIBRARY Xmu ${X11_LIB_SEARCH_PATH}) At least X11_LIB_SEARCH_PATH is what the code just above it defines, and when I make the above change by hand, configuration succeeds where it was failing. This was on OSX with XQuartz in /opt/X11.
Forgot to mention that this was with G4 10.0.p03.
This has been resolved in the current development, so a fix will be in the first patch for 10.1 and any further patches for 10.0
Did this actually make it to 10.00.p04? I re-experience the same issue there.
