How can I compile sqlite for WinRT / ARM?

Question

I've successfully compiled my WinRT version of SQLite for x86 as described by Tim Heuer.

However, I am still struggling how to compile the dll for WinRT on ARM CPUs. I've run nmake with the Visual Studio ARM command prompt, but that just gives me the following error:

 C:\sqlite>nmake -f makefile.msc sqlite3.dll FOR_WINRT=1 OPTS=/DWINAPI_FAMILY=WIN
API_PARTITION_APP

What am I doing wrong?

I finally managed to make this work:

1. Compiled the x86 dll as described here: http://timheuer.com/blog/archive/2012/05/20/using-sqlite-in-metro-style-app.aspx

2. Deleted only the sqlite3* files and the sqlitelib (many thanks to Banthar and Tim Heuer for the hint)

3. Compiled the ARM dll from the ARM VS command prompt with this command:

nmake -f makefile.msc sqlite3.dll FOR_WINRT=1 OPTS=/DWINAPI_FAMILY=WINAPI_PARTITION_APP
