Research direction

Start with build.libgit2.ps1 at line 71 and reproduce the build when cmake.exe is unavailable. Check how the empty result from Get-Command cmake.exe is handled, then run the script without CMake to verify it reports a clear, actionable error instead of an IndexOutOfRangeException.

Written by the indexing model from the issue text.

Description

Namely

.\build.libgit2.ps1 14
Index was outside the bounds of the array.
At C:\source\github.com\libgit2sharp\libgit2sharp.nativebinaries\build.libgit2.ps1:71 char:16
+     $cmake = @(Get-Command cmake.exe)[0] 2>$null
+                ~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], IndexOutOfRangeException
    + FullyQualifiedErrorId : System.IndexOutOfRangeException

which seems to come from @(Get-Command cmake.exe) returning an empty array.
