# include Makefile

#This file is included in the general Makefile, the libs Makefile and the src Makefile
#Different optimize settings for library and source files can be realized by using arguments
#Compiler optimize settings:
# -O0 no optimize, reduce compilation time and make debugging produce the expected results (default).
# -O1 optimize, reduce code size and execution time, without much increase of compilation time.
# -O2 optimize, reduce code execution time compared to ‘O1’, increase of compilation time.
# -O3 optimize, turns on all optimizations, further increase of compilation time.
# -Os optimize for size, enables all ‘-O2’ optimizations that do not typically increase code size and other code size optimizations.
#Recommended optimize settings for release version: -O3
#Recommended optimize settings for debug version: -O0
#Valid parameters :
# OptLIB=0 --> optimize library files using the -O0 setting
# OptLIB=1 --> optimize library files using the -O1 setting
# OptLIB=2 --> optimize library files using the -O2 setting
# OptLIB=3 --> optimize library files using the -O3 setting
# OptLIB=s --> optimize library files using the -Os setting
# OptSRC=0 --> optimize source files using the -O0 setting
# OptSRC=1 --> optimize source files using the -O1 setting
# OptSRC=2 --> optimize source files using the -O2 setting
# OptSRC=3 --> optimize source files using the -O3 setting
# OptSRC=s --> optimize source files using the -Os setting
# all --> build all
# libs --> build libs only
# src --> build src only
# clean --> clean project
# tshow --> show optimize settings
#Example:
# make OptLIB=3 OptSRC=0 all tshow
