VS: Use custom MSBuild.exe location

We are using custom location for msbuild.exe. However, CMake always takes msbuild.exe path from registry and override my property value.

bool cmGlobalVisualStudio10Generator::FindMakeProgram(cmMakefile* mf)
{
  if (!this->cmGlobalVisualStudio8Generator::FindMakeProgram(mf)) {
    return false;
  }
  mf->AddDefinition("CMAKE_VS_MSBUILD_COMMAND",
                    this->GetMSBuildCommand().c_str());
  return true;
}

std::string const& cmGlobalVisualStudio10Generator::GetMSBuildCommand()
{
  if (!this->MSBuildCommandInitialized) {
    this->MSBuildCommandInitialized = true;
    this->MSBuildCommand = this->FindMSBuildCommand();
  }
  return this->MSBuildCommand;
}

std::string cmGlobalVisualStudio10Generator::FindMSBuildCommand()
{
  std::string msbuild;
  std::string mskey;

  // Search in standard location.
  mskey = "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\MSBuild\\ToolsVersions\\";
  mskey += this->GetToolsVersion();
  mskey += ";MSBuildToolsPath";
  if (cmSystemTools::ReadRegistryValue(mskey.c_str(), msbuild,
                                       cmSystemTools::KeyWOW64_32)) {
    cmSystemTools::ConvertToUnixSlashes(msbuild);
    msbuild += "/MSBuild.exe";
    if (cmSystemTools::FileExists(msbuild, true)) {
      return msbuild;
    }
  }

  msbuild = "MSBuild.exe";
  return msbuild;
}

Could you please add the feature to set custom CMAKE_VS_MSBUILD_COMMAND property through -D CMAKE_VS_MSBUILD_COMMAND:FILEPATH=<path here> command line option and store it in CMakeCache.txt?
