Merge branch 'master' into 'master'

[cmake] fix capitalization of some SuiteSparse_ variables

There were still some variables with the old capitalization SUITESPARSE_
that prevented my own code from finding umfpack.h.

After this small fix, the code from merge request !8 works for me as expected.

See merge request !13
