Fix configuration error on systems without SuiteSparse installed
Issue was caused by the way how SUITESPARSE_FOUND was set and
used in IF conditions later. Basically, SUITESPARSE_FOUND was
setting to a value which needed to be expanded using ${} to get
it's actual value.
Made it so SUITESPARSE_FOUND is setting to either TRUE or FALSE
from an IF condition which does check for whether all the
dependencies are met.
Also removed expanding some of the variables in IF conditions,
they're not needed actually.
