# Template: lib and exe
# Use make variable_name=' options ' to override the variables or make -e to
# override the file variables with the environment variables
# 		make CFLAGS='-g' or make prefix='/usr'
# Instructions:
# - modify the section 1)
# - if you want, modify the section 2) and 3), but it is not necessary
# - modify the variables of the section 4): CFLAGS INCPATH ALL_CFLAGS CPPFLAGS LIBS
# - in section 10), modify the following action:
#		* all: and or remove exe and lib prerequisite
#		* lib: and or remove staticlib and dynamiclib prerequisite
#		* clean: add or remove the files and directories that should be cleaned
#		* install: add or remove the files and directories that should be installed
#		* uninstall: add or remove the files and directories that should be uninstalled
