How to compile example1.cpp


* Linux and macOS
  
  If you have installed Armadillo via the CMake installer:
  g++ example1.cpp -o example1 -O2 -larmadillo
  
  Otherwise, if you want to use Armadillo without installation:
  g++ example1.cpp -o example1 -O2 -I /home/blah/armadillo-7.200.3/include -DARMA_DONT_USE_WRAPPER -lopenblas
  
  The above command assumes that the armadillo archive was unpacked into /home/blah/
  The command needs to be adjusted if the archive was unpacked into a different directory
  and/or for each specific version of Armadillo (ie. "7.200.3" needs to be changed)
  
  If you don't have OpenBLAS, on Linux change -lopenblas to -lblas -llapack
  and on macOS change -lopenblas to -framework Accelerate


* Windows
  
  Open "example1_win64.sln" or "example1_win64.vcxproj" with Visual Studio.
  The example1_win64 project needs to be compiled as a 64 bit program.
  Make sure the active solution platform is set to x64, instead of win32.
