I was talking about querying such info without tweaking the CMakeLists.txt, just taking it as it comes from each project developer. Anyway, the info about required and optional dependencies is within the CMakeLists.txt of every project, and of course CMake gets all that info when building a project, so I'm guessing that, even if there's currently no command-line flag for telling CMake to dump to stdout the required or the optional dependencies, it shouldn't be hard to patch CMake for adding such flag, or alternatively writing a simple utility that does the job, linked with a small part of the CMake source code.

I don't think there's something that gives you exactly what you described, especially not for a random CMake project. If you can add some commands to the CMakeLists.txt, though, then the FeatureSummary module may suit your needs. Basically, you include the module an then add a cmake command like this: feature_summary(WHAT ALL FATAL_ON_MISSING_REQUIRED_PACKAGES) When you run cmake, you'll get a summary of which packages have been found/not found, and the required version if you supplied one for the corresponding find_package command.

[CMake] Querying project dependencies from the UNIX command-line
Hi! I've never used CMake (well, I'm continuously using it but as a user only, for building projects, not for maintaining them) . It's quite possible that I'll adopt CMake for maintaining my projects (I'm in the process of locating good references for learning "Modern CMake" --I want to start directly at Modern CMake, and avoiding as much old-fashioned practices as possible). However, before learning and adopting CMake, there's a feature that I need, and I don't know if CMake provides it, or if I'll need to use an additional tool for it. And that feature is querying dependencies. For example, I'd like to type "somecommand /path/to/someproject" at the UNIX command line, and get this output: Project /path/to/someproject requires the following to be built: wxWidgets >= 3.0.0 CUDA >= 7.0.0 OpenCV >= 3.3 Furthermore, if another command could show optional requisites, it would be really great: "anothercommand /path/to/someproject" Project /path/to/someproject can optionally use the following when being built: libtiff >= 4.0.0 libzip >= 1.5.0 So, can I get this functionality from plain CMake/CPack ? Or would I need additional tools (Note: I know about Hunter, but first I'd like to know if plain CMake does already offer this feature).
