Configuration failed while looking for unsolicited feature

[aminiussi]

I'm trying to use Ginkgo through a FetchContent, I do not specify any GINKGOBUILD* option, and I'm building with:

13:41:04 [alainm@pollux rel]# icpx --version
Intel(R) oneAPI DPC++/C++ Compiler 2023.1.0 (2023.1.0.20230320)

Ginkkgo version is 1.7.0.

My build is failing with:

So ok, maybe my oneAPI installation si broken. But I tried to configure with -DGINKGO_BUILD_SYLC=OFF, and got the same result. Is there a way to deactivate sycl with oneAPI ?

Thanks

You might have a typo in there, it should be -DGINKGO_BUILD_SYCL=OFF. At the same time, oneAPI is SYCL for our intents and purposes, so it doesn't make much sense to use oneAPI without SYCL enabled

[aminiussi]

Oh, that was dumb. Sorry!

No worries, I'm glad we could resolve this so quickly ;)
