You seem to be right that it's a package development question.
Currently, as long as there's a non-empty build log, OpenCL will show
it using R_ShowMesssage, or complain that it couldn't:

https://github.com/cran/OpenCL/blob/bcfcca930bffeac7f03f8ab1f9513d38fefe078b/src/ocl.c#L212-L224

I don't think that R_ShowMessage can be trapped in a portable way. In
the Windows GUI frontend, R_ShowMessage is implemented as a pop-up
window. If you run your program in Rterm, the log should be be printed
to the console instead of creating a pop-up window, so that could be a
quick (but far from perfect) workaround.

An improvement to the source code of OpenCL would be to replace the
R_ShowMessage calls with Rprintf("%s\n", message);, which at least can
be caught using capture.output().

I don't think that we have a C equivalent of message() (to be caught
using suppressMessages()). message() itself is implemented entirely in
R, both raising the condition and providing a default handler.
