# Makefile for installing MuST
#    The current directory (../MuST) has following sub-directories
#        architecture/ : contains architecture files for building MuST. The recommended name convention
#                        of an achitecture file is as follows: 
#                              system_name-compiler_name-MPI_name-GPU_status
#                        where system_name can be summit, bridges, frontier, etc.; GPU_status can be
#                        nogpu, gpu, amd, nvidia, etc.; compiler name can be intel, pgi, etc.; MPI_name
#                        can be mpich, openmpi, etc. If the compiler and MPI library are made by the same 
#                        ventor, e.g., Intel, compiler_name and MPI_name can be made into one character 
#                        string, e.g., intel.
#                        A templete "linux-gnu-openmpi-nogpu" is given as an example architecture file.
#        external/ : contains external libraries required or optionally required by MuST, 
#                   e.g., FFTW, Lua, P3DFFT, and LibXC.
#        lsms/ : contains LSMS and WL-LSMS codes targeted to extreme performance on petascale/exascale systems
#        MST/ : contains MST packages with wide physics capabilities, e.g. FP/MT KKR/LSMS/KKR-CPA, etc.
#
#    The steps to build MuST:
#        1. Create an architecture file and place it under architecture/.
#        2. make architecture_file_name
#        3. make install
