It is clear to me that out-of-source builds are better for many reasons, but I don't \
see how `cmake` dumping 3 pages of usage not mentioning anything about that lets user \
to understand that.

Moreover there is a lack of consequence whether path argument is obligatory or not, \
because `cmake -GNinja` or `cmake -DDUMMY=1` works in source directory without \
needing to specify extra dot.

In-source builds may be convenient too if you're working remotely via ssh in git \
managed folder, which I do a lot. This saves you lot of `cd` typing and it is quicker \
to do `git clean ...` than move forth and back to build folder.

If CMake is supposed to be meta-`make`, why it doesn't behave like `make`? If it \
suppose to help understand what is going on it should output rather:

===
CMake Warning: Current directory is source directory. Out-of-source builds are \
recommended. Specify `cmake .` to skip this warning or create separate build folder.
===

But I am really against that, since command line user shouldn't be treated like \
stupid user. Anyway for beginners GUI is preferred way to go.
