FIX: You receive LNK2001 and LNK1120 error messages when you use the Vcbuild.exe command-line tool to build a Visual C++ solution

When you use the Vcbuild.exe command-line tool to build a Microsoft Visual C++ solution, you receive the following error messages:
error LNK2001: unresolved external symbol Symbol Name
fatal error LNK1120: x unresolved externals
Note This problem does not occur when you use the Microsoft Visual Studio IDE to build the solution.
This problem occurs when all the following conditions are true:
  • The solution is dependant on one or more static library projects.
  • One or more of the required static library projects is in turn dependant on one or more additional static library projects.
  • Not all the static library projects are passed as link arguments in the Vcbuild.exe command-line tool.
Under these conditions, the Vcbuild.exe command-line tool cannot resolve the references to all the static library projects.
