==================================

1.Armadillo
	Before installing Armadillo, you could install LAPACK and BLAS with the following commands

	``sudo apt-get install libblas-dev``

	``sudo apt-get install libopenblas-dev``
	
	``sudo apt-get install libboost-dev``

	You could download the Armadillo with the apt package manager, but the version provided is really old, which is lower than our required version 10.3. So Download the package from the website 
	
	arma.sourceforge.net/download.html
	
	Extract the package and go to the armadillo folder, then open the ``CMakeList.txt`` file. Activate ``HDF5`` support by changing:

	``set(ARMA_USE_HDF5_ALT   false)`` to ``set(ARMA_USE_HDF5_ALT   true)``
	
	Then open a terminal and run:

	``cmake .``
	
	``make``
		
	``sudo make install``
	
	
2.OpenMP
	You could directly install OpenMP with the command below, which meets our version requirement 
	
	``sudo apt-get install libomp-dev``

3. HDF5
	You  could install 

	
3.cmake
	You could download the cmake package from the website
	
	https://cmake.org/files/
	
	Please make sure the cmake version is hogher than 3.10
	
4.VTK
	Download the VTK package (for example "VTK-9.0.1.tar.gz") from the link below:
	
	https://vtk.org/
	
	Extract the package and ``cd VTK-9.0.1``. 
	
	Create a folder named "build", and  ``cd build``. 
	
	Then ``ccmake ..``, you will come to interface shown as the picture below

	You could modify the configuration and press "c" to apply the changes (the default setting should be fine to run this application). Then press "g" to generate the "Makefile"
	
	After finishing the build step, a "Makefile" will be generated in the "build" folder. run ``make`` to complete the installation
