I fail to build TIFF code: it requires access to libtiff internals but it unavailable with libtiff prom ports. Probably pre build form thirdparty/tiff-4.0.3 should fix this, but I don't check this. Tiff code disabled for work but available in options. I fail with SSE2 too, there is some mess with class initialization: TRaster32P rout32 = rout; have no idea how to fix it. If some one want to play with it, then try to build with CFLAGS+= -DUSE_SSE2 -DDWORD=uint32_t -D_aligned_malloc=aligned_alloc -D_aligned_free=free on non windows system. FarmServer::queryHwInfo() - now uses TSystem::***() to collect system info, to avoid code duplication. Add pthread as required lib.
