Re: [Starpu-devel] Fwd: Informationn de starpu avec hwloc mais sans pkgconfig

[Nathalie Furmento <nathalie.furmento@labri.fr>]

configure.ac already has cases for packages which are found with or
without pkg-config. You cannot assume all libraries we are using are
provided with a pc file.

It is clear that if end-users want their packages to be detected
through pkg-config, then they need to make sure pkg-config is
available.

But here, it is requested to have hwloc detected through environment
variables, that needs to be allowed.

Cheers,

Nathalie
