function spqr_install (tbb)
%SPQR_INSTALL compile and install SuiteSparseQR
%
% Example:
%   spqr_install                        % compiles using METIS
%
% SuiteSparseQR relies on CHOLMOD, AMD, and COLAMD, and can optionally use
% CCOLAMD, CAMD, and METIS as well.  By default, CCOLAMD, CAMD, and METIS are
% used.  METIS is assumed to be in the ../../metis-5.1.0 directory.  If not
% present there, it is not used.
%
% You can only use spqr_install while in the SuiteSparseQR/MATLAB directory.
%
% See also spqr, spqr_solve, spqr_qmult.
