Error with cmake on windows

[RCJacH]

A year ago this worked and I was able to use reapack-index, until I reinstall windows due to system error. Currently I'm getting error installin reapack-index, due to failed installation of cmake (thus rugged).

Did you get these error by attempting to do gem install cmake manually? rugged needs the non-gem CMake: https://cmake.org/download/.

Select one of the "Add CMake to the system path ..." when installing. (You may need to restart opened command prompts afterward for the change to take effect.)

Yes I did ge tthe error by attemping to do gem install cmake. I installed the non-gem CMake, and ran gem install reapack-index, now the error is:

checking for make... no ERROR: GNU make is required to build Rugged. extconf.rb failed Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Make should have been installed as part of the Ruby post-installation (msys2). Launch "ridk install" and pick the option 3.

Thank you, it's working now after I installed msys2, although I still don't know why it was stuck since I had it installed many times.
