My attempt to build a 32-bit CMake failed because I can’t find 32-bit build tools on a reasonably ancient OS. In particular, the 32-bit build tools for the CentOS you use to build the 64-bit version are no longer available on any public or private repository I could find.
I ended up doing something I really don’t like: I downgraded to CMake release 3.6.3, which was the last one you published with a 32-bit installer. I now cannot use any of the nice things you added to CMake since 2016, just because I have to support 32-bit builds!
