Can you build a SharePoint Project without Visual Studio 2010/2012 being installed on the machine you are trying build it on using PowerShell?
I have a PowerShell script the is working great. It calls up SlikSVN hits my repository checks the code I want out and builds it using MSBuild.exe. Granted that this machine has Visual Studio 2012 installed on it and SharePoint Foundation 2010 as well. When I try to run the script on a machine with just SharePoint Foundation 2010 installed I get a few errors. I was able to suppress some by copying varying folders and files over, but now I am stuck with an error I cannot resolve.
Error in powershell:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\SharePointTools\Microsoft.VisualStudio.SharePoint.targets(4 80,5): error MSB4066: The attribute "BeforeTargets" in element is unrecognized.
After I installed the .Net 4 Framework and Win SDK I get this error. I cannot remember if I copied this folder: (C:\Program Files(x86)\MSBuild\Microsoft\VisualStudio\v10.0\SharePointTools) from my Dev machine or not. It seems like I need to some how register the DLLs but I tried Regsvr32.exe with no luck.
