cant compile ETM

hi Nauk,
ive been struggling fixing the ETM source file errors then i finally fixed them all but now i stumbled in this linking error :
1>------ Build started: Project: EditableTerrainManager, Configuration: Release Win32 ------
1>LINK : fatal error LNK1181: cannot open input file 'C:\OgreSDK_vc10_v1-7-4\lib\EditableTerrainManager.lib'
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
i have included the directories but i dont have the EditableTerrainManager.lib file , how can i fix that?
thx in advance,
Romulo Romero

For future reference - just remove everything from the Custom Build Step option in the project.
