While working on [#209], I got a segfault when importing the Python module somewhere in libcblas. My guess is that somehow I linked in a CBlas library with Wavepacket, while numpy used another one, and something got screwed up.
This whole problem can in principle be overcome with the new CMake-based port of the tensor library. Here, I can link in all Blas statically with vcpkg and have no dependency on Blas whatsoever.
This needs adaptions in the CMake code, and additional documentation and smaller fixes, on the side of the tensor library as well as in Wavepacket.
Still leftovers, but in principle everything works with the CMake port. The cmake-based libtensor also got a bunch of improvements to run with the native openBlas on Debian at least.
