Fixes #6628
The background for this is described in much greater detail in #6628 (comment).
In short:
{data.table}recently put up a new release (v1.16.0)libomp.dylib{data.table}and a CMake + clang version of{lightgbm}to load 2 different copies oflibomp.dylib, causing segfaults{lightgbm}are brokenThis fixes it by ensuring that the place where R vendors third-party libraries is searched for
libomp.dylibfirst whenlibrary(lightgbm)is called (so that the same libraries used by CRAN will be found).Notes for Reviewers
