# Primesense template makefile.
# This file should not be made, but only included from other makefiles.
# By default, this makefile compiles in release. To compile a debug version:
# make CFG=Debug
#
# Project makefile should define the following BEFORE including this file:
# SRC_FILES - a list of all source files
# Output name under one of the following:
# EXE_NAME (executable),
# LIB_NAME (dynamic library) or
# SLIB_NAME (static library) or
# BIN_DIR - Bin directory (output dir)
# INC_DIRS - a list of additional include directories
# LIB_DIRS - a list of additional library directories
# USED_LIBS - a list of libraries to link with
# DEFINES - [Optional] additional preprocessor defines
# CFLAGS - [Optional] additional flags for the compiler
# LDFLAGS - [Optional] additional flags for the linker
# SSE_GENERATION - [Optional] The SSE generation to use (default is 3)
# TARGET_SYS_ROOT - [Optional] The path to the root of the target
# ALLOW_WARNINGS - [Optional] Allow warnings during compilation
