You don't need to run meson twice.  You can just add -Dprefix=/tmp/install
to the first meson line.

For Vulkan, LD_LIBRARY_PATH and LIBGL_DRIVERS_PATH do nothing.  What you
want is

VK_ICD_FILENAMES=/tmp/install/share/vulkan/icd.d/intel_icd.x86_64.json

That's because libvulkan.so is provided by the loader which should be
installed by your OS.  You don't need to rebuild the loader to try out new
driver builds.
