[vtkusers] Using vtkMy

[Mike Jackson]

If you look in the FindVTK.cmake file (included in the cmake  
distribution) then you will see that they are probably defining any  
include directories that need to be included. Also, if you do an  
actual build and Install of VTK then vtk puts all the include files  
in a single directory so there is no need for something like:

#include <vtkIO/vtkBMPReader.h>
instead you can use
#include < vtkBMPReader.h>

This is a matter of personal opinion which way is better and I am not  
going to start a debate which way is better. If you have your sources  
broken up into lots of subdirectories then you have some choices.

You can #include <Common/SomeCommonHeader.h> in which case you only  
need the following in your cmakelists.txt file
INCLUDE_DIRECTORIES( "../vtkMy/")

You can #include <SomeCommonHeader.h> in which case you will need the  
following in your cmakelists.txt file
INCLUDE_DIRECTORIES( "../vtkMy/Common"

I personally prefer the first approach as it makes it clear to a new  
user coming to your code where to find the header file.

Good Luck.

For an example of how I have setup my code base have a look at http://
