# This file contains make file commands that are common to all the c++ classes
# in this project includein GeoTessCPP, LibCorr3D, GeoTessAmplitudeCPP, GeoTessCShell,
# and GeoTessAmplitudeCShell.  All those applications have Makefiles that set
# variables APP, TARGET, INCLUDES, LIB, DEPENDENCIES and SRC and then include this file.
