Hi One more thing. There is huge difference in Unix Makefile generation time between 32 vs 64 bit cmake version:
32 bit CMake 3.5.0 generation time: real 5m33.310s user 5m27.268s sys 0m3.540s 64 bit CMake 3.5.0 generation time: real 2m36.457s user 2m32.008s sys 0m3.184s Unfortunately there no 64bit CMake version for Windows: https://cmake.org/download/ Is it possible to create 64 bit build for Windows?
