So you are refering to the dolfin extension modules (expressions, 
compile_subdomains) not ufc extension modules (from ufl forms)?

jit compilation of dolfin extension modules get the dolfin flags from pkg-
config. Everything that is in dolfin.pc gets included in the appropriate 
flags. If the path to the blas library was included there it should just work.

Any suggestion on how this can be done properly? CMake lack a good way to get 
the flags from the command prompt, and hence from within instant. Here pkg-
config is nice. 

What is problematic with pkg-config? Sure it is not the generation of the pkg-
config file that is flawed?
