Paths that start with a word in angle brackets are relative to the installation prefix. I.e. <share>/pixmaps/ refers to <share>/pixmaps if GDM was configured with --prefix=/usr. Normally also note that GDM is installed with --sysconfigdir=<etc>/X11, meaning any path to which we refer to as <etc>/gdm/PreSession usually means <etc/X11>/gdm/PreSession. Note that for interoperability it is recommended that you use a --prefix of /usr and a --sysconfdir of <etc>/X11.
