Bugzilla Automation <bugzilla at FreeBSD.org> has asked freebsd-kde (Team)
<kde at FreeBSD.org> for maintainer-feedback:
Bug 257321: math/eigen3 drop OpenBLAS dependency, this is a template library
that has no compilation per the build requirements
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257321



--- Description ---
https://eigen.tuxfamily.org/index.php?title=Main_Page#Requirements

Requirements

Eigen doesn't have any dependencies other than the C++ standard library.

We use the CMake build system, but only to build the documentation and
unit-tests, and to automate installation. If you just want to use Eigen, you
can use the header files right away. There is no binary library to link to, and
no configured header file. Eigen is a pure template library defined in the
headers. 




there is no reason why this has OpenBLAS as a required library. This should
also close PR 251842, for the same basic reason. Nor would it seemingly need
any of the other listed library dependencies
