CMake 3.3.2 solves a fundamental and quite nasty CMake find regression that occurred from 3.2.0 through 3.3.1. See threads entitled "[BUG] HINTS not correctly handled in find_program" and "find_program HINTS no longer preferred over PATH" on the cmake-devel list. I think this regression will not affect users who only have the system versions of libraries to find in the standard locations, but more sophisticated users who are perhaps building their own sets of libraries that are not installed in system locations could run into find trouble. So it is not a showstopper regression, but still it makes any bug report specified for that range of CMake versions somewhat suspect in case the error reported is a result of this find regression so to simplify my life I prefer not to support the above CMake version range at all.
I have not yet had a chance to try 3.3.2 because of some computer troubles I am still diagnosing (although it is likely a new disk drive, Debian install, and restore from backup is in my near future). However, Greg does report success with CMake-3.3.2 on MinGW-w64/MSYS2 so I encourage everyone here to give it a try also. The current status is our minimum version of CMake is 3.0.2 for Linux and Cygwin and 3.2.3 for everybody else. Once my computer is healthy again, and I can demonstrate no problems with CMake-3.3.2 on Linux, I plan to change our build system to issue a warning message about using any version of CMake from 3.2.0 through 3.3.1 if any of those versions are detected for our Linux and Cygwin users. For everybody else I plan to avoid the issue altogether by bumping our minimum CMake version to 3.3.2. Let me know if there are any strong objections to this plan for dealing with the above regression. Alan __________________________ Alan W.
