Nothing violates GPL if the linked code is not being distributed (see the GPL 

Furthermore, copying code from one computer to another inside the same 
organization is NOT considered to code distribution according to the GPL FAQ.

So, "just do it". I.e. replace FFTW with CUDA equivalent, and BLAS with cuBLAS 
and use it in the comfort of yor home or organization.
