About cufft_test folder

On Ubuntu, BLAS and LAPACK can be installed in one command:

	sudo apt-get install liblapack-dev -y ; sudo apt-get install liblapack3 -y ; sudo apt-get install libopenblas-base -y ; sudo apt-get install libopenblas-dev -y ;

Therefore, include library in the Makefile like:

	g++ ... -L/usr/lib -llapack -lblas
