[  0%] Built target libclarabel_c

right after all rust crates are compiled and before the C libs are

I have also seen this warning when building and could not determine the cause. It is not (I think....) an actual error, since it seems that the associated types do actually exist and work in the unit tests.

I would be happy to be told otherwise though, in which case I will try again to fix. Alternatively, happy to accept a PR if someone is able to resolve it.

Fixed by #67

[goulart-paul]

I think this should be fixed now.

Note that I have rewritten the cmake build options to allow direct specification of features for the underlying rust solver. So something like this now:

cmake -DCMAKE_BUILD_TYPE=Release -DCLARABEL_RUST_FEATURES="sdp-openblas,serde"  ..

It should be backward compatible to the old way of specific features one at a time via cmake options though.

Please reopen / open another one if something is still broken.
