The Trilinos Project is an effort to facilitate the design, development, integration and ongoing support of mathematical software libraries.

The Trilinos Project is an effort to facilitate the design, development, integration and ongoing support of mathematical software libraries. In particular, our goal is to develop parallel solver algorithms and libraries within an objectoriented software framework for the solution of large-scale, complex multi-physics engineering and scientific applications. Our emphasis is on developing robust, scalable algorithms in a software framework, using abstract interfaces for flexible interoperability of components while providing a full-featured set of concrete classes that implement all abstract interfaces.

build pytrilinos using trilinos version already installed

I have access to a cluster where trilinos is already statically built. Is it possible to build just pytrilinos myself linking to those libraries? or the only way is to built all of trilinos from source? thanks!
