## NOTE: To use Armadillo without installation, compile your programs along these lines:
## NOTE: g++ prog.cpp -o prog -O2 -I /home/blah/armadillo-7.200.3/include -DARMA_DONT_USE_WRAPPER -lopenblas -llapack
## NOTE: The above command line assumes that you have unpacked the armadillo archive into /home/blah/
## NOTE: You will need to adjust this for later versions of Armadillo (ie. change the 7.200.3 part)
## NOTE: You will need to adjust this for newer versions of Armadillo (ie. change the 7.200.3 part)
## NOTE: and/or if you have unpacked the armadillo archive into a different directory.
## NOTE: Replace -lopenblas with -lblas if you don't have OpenBLAS.
## NOTE: On macOS, replace -lblas -llapack with -framework Accelerate
