Verifying dependencies
nimble install -d
   Warning: Package 'heimdall' has an incorrect structure. It should contain a single directory hierarchy for source files, named 'heimdallpkg', but file 'bitboards.nim' is in a directory named 'heimdall' instead. This will be an error in the future.
      Hint: If 'heimdall' contains source files for building 'heimdall', rename it to 'heimdallpkg'. Otherwise, prevent its installation by adding `skipDirs = @["heimdall"]` to the .nimble file.
