Help With Moving Files Before Nimble Package Installation

[Niminem]

Hey guys,

I'm trying to move a 3rd party binary to the .nimble/bin directory before 
installing my package via Nimble but I'm having issues--

Code within .nimble file: 
    
    
    before install:
        let command = "move " & getCurrentDir() / "windows" / "rcedit-x86.exe" 
& " " & getHomeDir() / ".nimble" / "bin" / "rcedit-x86.exe"
        echo command
        exec(command)
    
    
    Run

Output: `Error: unhandled exception: The system cannot find the file specified. 
[OSError]`

Any idea here on what could be going on? I copied/pasted the string that the 
command variable contains into the terminal- works fine on its own.
