Problem installing UMPACK, CHOLMOD, KLU, and SuiteSparseQR in Matlab R2018a

[AntonSemechko]

Describe the bug
UMPACK, CHOLMOD, KLU, and SuiteSparseQR not being installed due to recurrent error with \metis-5.1.0\gk_arch.h (screen shot attached)

To Reproduce
Enter SuiteSparse_install into Matlab command window

Expected behavior
All components of SuiteSparse should install\compile without errors

This is a limitation of metis, which I can't work around. To resolve it, simply compile without it. You can do this just by deleting the metis folder from SuiteSparse.

Thank you for the prompt response!

I followed your suggestion. KLU was successfully compiled as a result, but installations of UMFPACK, CHOLMOD, and SuiteSparseQR still failed due to following errors in the umfpack_make.m, cholmod_make.m, and spqr_make.m files when calling mex

gcc: error: libmwlapack.lib: No such file or directory
gcc: error: libmwblas.lib: No such file or directory

That's not a problem with SuiteSparse, but with MATLAB. Those are libraries that MathWorks provides with MATLAB, but in each release of MATLAB, they change how to link against them. I can't keep up with their changes, unfortunately. The MATLAB documentation might provide some guidance on how to link against LAPACK and the BLAS libraries.

Ok, I will look into that. Thanks for your help!
