mint build - doesn't work when public dir has a sub folder

[kingsleyh]

Hi

I pulled the latest mint and built it after upgrading to crystal 0.25 - but when I run mint build I get the following error:

Clearing the "dist" directory... 1.034ms
Unhandled exception: Error reading file: Is a directory (Errno)
  from File@Crystal::System::FileDescriptor#unbuffered_read<Slice(UInt8)>:Int32
  from FileUtils@FileUtils::cp<String, String>:Int32
  from Mint::Builder#initialize:Nil
  from Mint::Cli::Build#parse_and_run:Nil
  from __crystal_main
  from main
⚙ Copying public folder contents...

These are the only files I have in my project dir:

I think I've found the issue - it's because I have a directory inside the public directory. The current glob doesn't seem to cope with sub directories:

FileUtils.cp Dir.glob("public/**/*"), "dist"
