Problem
Running the
idl build
command when there is only one program inside the workspace root results in an error:$ anchor idl build Error: Not in a program directory
You need to specify which program's IDL to build if the current directory is not a program directory:
This is unnecessary when there is only one program in the workspace.
Summary of changes
