Build error in the v6-26-00-patches branch

This is Ubuntu 20.04 LTS / x86_64 / gcc, g++, gfortran 9.3.0 / cmake 3.16.3 here. The building of the current “v6-26-00-patches” branch (as of 2022.03.06) generates an error (in any version, “--std=c++14” and “--std==c++17”):

You are probably missing the definition of Vc_1::Common::checkLibraryAbi(unsigned int, unsigned int, char const*)
Maybe you need to load the corresponding shared library?
Symbol found in '/.../v6-26-00-patches-cxx14/lib/'; did you mean to load it with '.L /.../v6-26-00-patches-cxx14/lib/'?

Actually, the same error has been reported half a year ago for the "v6-24-00-patches” branch:

Indeed. We tried to fix it in and but that caused failures that were worse than this error message. @vvassilev maybe you can share your plans for this?

The two warnings about redefined Vc macros are also still there (in “v6-26-00-patches”).
