Unable to locate ninja

[EgorBo]

Previously, it was enough to invoke the eng/common/native/./install-dependencies.sh script on a clean Linux OS (e.g. Ubuntu 24.04) to build the runtime. Now it fails with

  __TargetRid: linux-arm64
  Setting up directories for build
  Checking prerequisites...
  Unable to locate ninja!

It should not be required or be installed by install-dependencies.sh

@steveisok probably #124041 ?

We updated it in arcade, but it needs to flow to the VMR in dotnet/dotnet#4714 and then back to runtime.

Is this too disruptive for you? If so, we can revert #124041 and wait until the backflow completes.

@akoeplinger merged dotnet/dotnet#4714. Let's see how fast that comes back into the existing backflow PR in #124095 and try to get that in.

Absolutely not disruptive, just wasn't aware of it. Added apt install ninja-build for now in my script
