[Mesa-dev] Trying to build a opencl dev env

[Pierre Moreau]

Hello Luke,

If you set `PKG_CONFIG_PATH=$PATH_TO_LIBCLC_INSTALL/share/pkgconfig` when
running meson, it should pick that version instead of the system one.

I run it as `PKG_CONFIG_PATH=[…] meson setup […]`; it might also be possible to
pass it as an argument instead, I do not know.

Best,
Pierre
