DFM not found after reorganisation

I have a Delphi 7 project with this structure:

.dpr
foo.pas
*.pas
*.dfm
Bin/
debug/

Most of the source code, except for one file, is shared between other projects (although this is not relevant), so I did some reorganisation that looks like this:

.dpr
UniqueFile/
    foo.pas
Common/.pas
    *.pas
    *.dfm
Bin/
debug/

I changed the paths in the .dpr with the new structure, but when I try to compile for some reason it cannot find one of the .dfm files in Common folder. The error shown is:

[Error] File not found: 'SomeFile.DFM'

However, both the .pas and the corresponding .dfm are in that folder.

Did I miss some configuration?

EDIT: This file is included in the .dpr file like so:

uses
   ...
   SomeFile in 'Common/SomeFile.pas',
   ...

EDIT2: I've copied only the SomeFile.dfm file to the root folder, and it's compiling. For some reason it's still looking for that file in the old path?

EDIT3: I've included what @ken-white has pointed out but no luck. So now the .dpr looks like so:

uses
   ...
   SomeFile in 'Common/SomeFile.pas' {ChildFrame},
   ...

I've also double-checked this line in SomeFile.pas:

{$R *.DFM}

Another thing that I should point out is that the Build option works fine, but not the compiling.

Solution

Looks to me that your issue (at least as of now) is that you are using a forward slash instead of a backslash.

uses
   ...
   SomeFile in 'Common/SomeFile.pas' {ChildFrame},
   ...

...should instead be...

uses
   ...
   SomeFile in 'Common\SomeFile.pas' {ChildFrame},
   ...
