# CMAKE File for "MyApp" application building against an installed Trilinos

#This file is an adaptation of the CMakeLists.txt file that was converted from 
#the buildAgainstTrilinos example. This Makefile was designed to be used in a
#flat directory structure. If you would like to run this example you will need
#put this file and src_file.cpp, src_file.hpp, main_file.cpp from
#buildAgainstTrilinos into a new directory. You will then need to set the
#environment variable MYAPP_TRILINOS_DIR to point to your base installation of
#Trilinos. Note that this example assumes that the installation of Trilinos that
#you point to has Epetra enabled.

# Get Trilinos as one entity
include $(MYAPP_TRILINOS_DIR)/include/Makefile.export.Trilinos

# Make sure to use same compilers and flags as Trilinos
