Makefile weirdness

[pmeerw]

CC = g++
is a bit weird, generally CXX refers to the default C++ compiler
to make it more cross-build frieldly, I'd suggest CXX ?= g++

AdsLibTest.bin: $(LIB_NAME)
$(CC) AdsLibTest/main.cpp $< -I AdsLib/ -I ../ -std=c++11 $(LIBS) -o $@
is a bit weird, why not
AdsLibTest.bin: $(LIB_NAME) main.o
$(CC) main.o $< -I AdsLib/ -I ../ -std=c++11 $(LIBS) -o $@
so all .o are build by the .cpp.o rule
is -I ../ needed?
I think -I and std=c++11 can be dropped when purely linking

use $(AR) instead of plain ar (cross-build)
