Missing operator= in code generated by MakeProject #8987
Description
In case where the class generated by MakeProject derived from a class that deletes the operator= then in some compiler we get the error below (which is expected since the class generated by MakeProject has a copy constructor which is needed by stl collection).
SRChh_ROOT6_mcgenProjectSource.cxx: In copy constructor ‘KKceex::KKceex(const KKceex&)’:
SRChh_ROOT6_mcgenProjectSource.cxx:922:54: error: use of deleted function ‘KKpart& KKpart::operator=(const KKpart&)’
