Build Project

Please ensure you have set BOOST_ROOT in this shell

> mkdir ./build
> cmake .. 
> make 

Compiling

To use Boost_USE_STATIC_LIBS and Boost_USE_STATIC_RUNTIME are set on in the config but you can always add :

-DBoost_USE_STATIC_LIBS=ON -DBoost_USE_STATIC_RUNTIME=ON

To enable debug use :

-DBoost_DEBUG=on

Clean the project:

Set the BOOST_ROOT to the correct value.

> rm -rf ./build && mkdir ./build && cd ./build &&  cmake ..
