The find_package command docs [1,2] recommend that user code should generally look for packages using the Module mode signature. What then about user code that ought to check for version compatibility? Module mode only offers a check for an EXACT version string, and does not terminate if that condition is not met [3]. Users who need a newer-than or same-major version check, or a strict enforcment of an exact-version check, are advised to prefer packages that use CMakePackageConfigHelpers to generate FooConfig[Version].cmake files. These files, however, are ignored unless Config mode is chosen.
Is this summary correct? Shouldn't then the general recommendation of Module mode be qualified? - Joachim [1] https://cmake.org/cmake/help/v3.12/command/find_package.html [2] https://gitlab.kitware.com/cmake/cmake/merge_requests/2446 [3] https://stackoverflow.com/questions/52633455
