Hello!

Nathalie Furmento <nathalie.furmento@labri.fr> skribis:

IIUC it’s the environment variable that tells where to look for OpenCL
implementations that’s only supported by OCL, right?

> The problem is how we make sure that implementation is installed on

If that libraries defines specific macros, or exports specific symbols,
‘configure’ could check for them.

Thanks,
Ludo’.
