The source project of this merge request has been removed.
Make symbols visible when .git directory exists.
Newer versions of perf do not print hidden symbols. This causes us to lose lots of good information in the perf report for VTK-m.
As a side note, should we change the name of VTKm_USE_DEFAULT_SYMBOL_VISIBILITY? It requires the user to know what the default is (visible); perhaps VTKm_MAKE_ALL_SYMBOLS_VISIBLE or VTKm_HIDE_PRIVATE_SYMBOLS would be more user-friendly?
