Just run this little script:
sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get -y install git make libtool autoconf libcurl4-openssl-dev libudev-dev
git clone https://github.com/ckolivas/cgminer.git
cd cgminer
sudo ./autogen.sh
sudo ./configure --enable-bflsc
sudo make
sudo make install
sudo cgminer
