function gbmake (what)
%GBMAKE compile @GrB interface for SuiteSparse:GraphBLAS
%
% Usage:
% gbmake
%
% gbmake compiles the @GrB interface for SuiteSparse:GraphBLAS. The
% GraphBLAS library must already be compiled and installed.
% MATLAB 9.4 (R2018a) or Octave 7 later is required.
%
% For the Mac, the GraphBLAS library must be installed in /usr/local/lib/ as
% libgraphblas_matlab.dylib. It cannot be used where it is created in
% ../build, because of the default Mac security settings. For Unix/Linux, the
% library used is ../build/libgraphblas_matlab.so if found, or in
% /usr/local/lib if not found there.
%
% See also mex, version, GrB.clear.
