Beyond that the difficulty lies in that calling any command lacks consistency and the output is just that some global variable without any convention were reassigned. There is no common semantics so you can not take the knowledge you learned from one operation and apply to the next one, everything is unique and non-composable. The solution to almost everything is just paste this random magic string anywhere in your cmakelist and it will work.
I do fantasize about a new Cmake frontend implemented with Tcl scripting. That would be far more consistent and flexible and you can disable much of the language by default to minimize footbullets then allow commands to be reenabled for times they're needed.
This would of course be a huge improvement, but there are many details to get right to support the old and new scripts in parallel to effect a smooth transition. But in the long term, this will resolve many complaints about CMake and really improve the semantics of the language and development and debugging of scripts.
I propose that it doesn't support build generators. It should do the build itself, like QBS did.
It's great that one person can be using Visual Studio on Windows while another uses CLion on MacOS and another uses Eclipse or Emacs on Linux, all working on the same codebase. It's a huge benefit for cross-platform tooling-independent development.
I'm confused. How do you propose CMake supports all those build generators without doing this?
(PS. I really don't think the syntax is that bad, aside that it is jarring for C programmers, most complaints are overblown and you get used to it once you learn the rules. It might be interesting if someone made a CMake variant with a less obscure syntax but I don't see much motivation for that to actually happen)
