Examples don't work when installation instructions are followed (.local)

[MLopez-Ibanez]

The documentation suggests:

cmake -DCMAKE_INSTALL_PREFIX=~/.local .

However, none of the examples will work this way because GCC does not search in ~/.local by default. Every example must be amended to use something like:

g++ -c -O2 -DNDEBUG -std=c++11 nsga2.cpp -I $HOME/.local/include -o nsga2.o
g++ -O2 -DNDEBUG -std=c++11 nsga2.o  -L $HOME/.local/lib  -lpagmo -Wl,-R$HOME/.local/lib  -o nsga2
