C:/Geant4/geant4_9_3_p01/data/G4EMLOW6.9  looks like a reasonable value for  G4LEDATA

You do not set this in a makefile. It specifies somewhere where the code is to access data when running, not when being compiled.

I suspect that it is already set for you. Open a Cygwin window and type
set
and see whether it outputs a line like
G4LEDATA=C:/Geant4/geant4_9_3_p01/data/G4EMLOW6.9
(along with many other lines). If it does not, try to find a file named something like  env.sh  and  cd  to its directory and type
. ./env.sh
Along with many other lines, that should output something like
"On this machine the G4LEDATA=C:/Geant4/geant4_9_3_p01/data/G4EMLOW6.9"
If that does not work, then you could try typing
export G4LEDATA=C:/Geant4/geant4_9_3_p01/data/G4EMLOW6.9
instead of
setenv G4LEDATA "/usr/local/geant4/data/G4EMLOW4.3"
