[Cmake] Problem with LoadCommand

[John Biddiscombe]

When a project uses vtk by loading the FindVTK module and then inclusing the
correct USE_VTK file, the use vtk stuff doesn't load any custom commands
that vtk uses, like VTK_WRAP_TCL2.

I'vce tried loading this myself, but it access violates every time I try.
Could someone advise what I need to do. I'm currently doing

LOAD_COMMAND(VTK_WRAP_TCL2 "D:/cmakebuild/vtkDebug/CMake" "don't know what
this one is")

the directory is correct for the dll

when I use this

LOAD_COMMAND(VTK_WRAP_TCL2
"D:/cmakebuild/vtkDebug/CMake/cmVTK_WRAP_TCL2.dll"
"D:/cmakebuild/vtkDebug/CMake/cmVTK_WRAP_TCL2.dll")

it says, "attempt to load command failled from ...dll"

What is the correct syntax. I'm afraid the docs aren't much help and looking
at the code I can't see the problem.
