It is. If BLAS is not found, a BLAS subset in the libcruft directory
is used, probably insufficient for CHOLMOD. The configure script
correctly reports that your CHOLMOD installation isn't working,
whatever the reasons are.

Most likely it can't find libraries at runtime. Discovering the
sizeofs is the first check
that requires not only compiling a test program but also running it.
If you have libs in non-standard locations, maybe you'll want to use
-L <path> as well as pass -Wl,--rpath=<path> to the linker (hardcodes
the search path into the executable).
