rust-analyzer: Failed to run build scripts of some packages

[EvilWatermelon]

I'm new with the rust-analyzer and after my successful installation I'm always getting this output from the analyzer:

FetchBuildDataError:

How can I fix these errors? - I know that these are errors from compiling a crate but the program can execute without any errors.

[lnicola]

  CMAKE = None

Maybe you need to install CMake? Without it, I get:

  Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
  thread 'main' panicked at '
  failed to execute command: No such file or directory (os error 2)
  is `cmake` not installed?

Except for the last one, those errors come from the paho-mqtt-sys build script, not from us. I suspect a plain cargo check will fail for you just as well.

[EvilWatermelon]

Ok, the messages are gone now. I ran a cargo check and it seemed that I had to restart my computer.

[lnicola]

Toll!

As for the last error, it looks like #5366.
