Reseek uses the amazing parasail library parasail library https://github.com/jeffdaily/parasail (thanks Jeff!) for fast Smith-Waterman. Currently it fails to compile on Intel Mac. Reseek uses only a small subset of parasail functions which are copy / pasted into the Reseek source code, bypassing parasail's CMake infrastructure. The fix is probably a straightforward tweak of header includes and compiler options which can be inferred by comparing with the Makefile generated by CMake.
Would be great if any volunteers want to tackle this one!
