The problem you see while using `-Dvulkan-drivers=libre-soc` is because
upstream mesa git repo does not have libre-soc related source code.
It lives here
and soon I will push the same code on libre-soc git repo.
So please give above source a build try with `-Dvulkan-drivers=libre-soc`
in meson configuration command
on successful build and install you should see a json file for libresoc
vulkan driver in <install_dir>/share/vulkan/icd.d path like following:
vivek at vivek-VirtualBox:~/install/share/vulkan/icd.d$ ls

and libvulkan_libresoc.so file in <install_dir>/lib/<folder_name_basedon_OS
_and_arch> like following:
vivek at vivek-VirtualBox:~/install/lib/x86_64-linux-gnu$ ls
dri              libglapi.so.0.0.0      libGL.so.1.2.0
libEGL.so        libGLESv1_CM.so        libvulkan_libresoc.so
