meson actually accepts prefix , so I use it like this (from BUILD dir inside
mesa tree):

meson ../ --prefix=/usr/X11R7 rest_of_options (obviously, for x86-64 prefix
will be diffeent, I just wanted to say I have non-standard X prefix and install
mesa into it just fine)

full line in my case looks like:
meson ../ --prefix=/usr/X11R7 --strip --buildtype debugoptimized -Degl=true
-Ddri-drivers=r100,r200,i965,nouveau -Dplatforms=drm,x11
-Dgallium-drivers=i915,r600,radeonsi,swrast,virgl,nouveau,r300
-Dvulkan-drivers=amd,intel  -Dgallium-nine=true -Dgallium-opencl=icd
-Dgallium-va=true -Dgallium-xvmc=true -Dgallium-xa=false

You probably want to add --reconfigure if you re-run meson after some git pull
from same BUILD directory.
