Test characteristics of dependencies (esp. LAPACK) when compiling shared libs

[Paul Wilson]

On some systems, the LAPACK library is only available as a static library and may not be built with options (e.g. fPIC) that allow linking to a shared library. It would be helpful to test this, if possible, during configuration (CMake or autotools) rather than failing at build time.

This is a tricky requirement. I may not have a clean solution that works everywhere. Do you have suggestions to address the problem ?

[Paul Wilson]

I don’t have any suggestions - just observed this on some systems. I actually can no longer remember where I saw this….
