openpgl exposes embree::mm_lookupmask_ps symbol

[StefanBruens]

The mm_lookupmask_ps/mm_lookupmask_pd symbols are visible from libpgl:

nm -DC --defined-only /usr/lib64/libopenpgl.so.0.4.0  | grep embree
0000000000078580 B embree::mm_lookupmask_pd
0000000000076060 B embree::mm_lookupmask_ps

https://github.com/OpenPathGuidingLibrary/openpgl/blob/a1404c528b9586acdf55fc150b1cb16ab55f6bab/third-party/embreeSrc/common/simd/sse.h#L24-L25

libembree3 proper does not have this issue, as it sets default symbol visibility to "hidden".

@StefanBruens, thanks for pointing that out.
I will make sure that it will be part of the next release.

Hi @StefanBruens

could you try and see if the fix/linux-arm-and-visibility branch fixes your problem?

[StefanBruens]

The options are only applied when you use a RELEASE build:
0ef25a1#diff-54334ebcaf9c58cca1d6b08404b95dcfe68b84a3bedaafbfab42fe76606b3aedR135

For Linux distributions the typical CMAKE_BUILD_TYPE is RelWithDebInfo, i.e. optimized with debug symbols.

The compiler option variables should be probably split into "common" and debug/release ones, and the common ones should be added to the target_compile_options for all CONFIGs.
