Make the changes in the script, before you start the build. These changes will be visible in any child process. 
sub Build
{
  # my $vcvars32 = 'VCVARS32.BAT';  << comment out these 
  # system ($vcvars32);             << two lines

  # set your environment variables (the same ones 
  # vcvars32.bat sets) like so:
  
  $ENV{LIB}  = 'D:\MSVCDIR\LIB;'.$ENV{LIB};
  $ENV{PATH} = 'D:\MSVCDIR\BIN;'.$ENV{PATH];
  
  system $command;  # this now sees the variables set above
