[CMake] Can't find INCLUDE file...

[rnelias]

Hi folks, I'm having a problem that seems to be very simple...

I'm trying to compile a program which INCLUDES the following headers

//--------------------------------------------------
#include "vtkGenericEnsightReader.h"
#include "vtkXMLDataSetWriter.h"
#include "vtkDataArrayCollection.h"
#include "vtkDataArray.h"
#include "getpot.h"
...
//--------------------------------------------------

Note that only getpot is not a VTK include.

In order to compile this program I'm using the following CMakeLists.txt

//--------------------------------------------------
PROJECT (ens2vtk)

FIND_PACKAGE(VTK REQUIRED)
INCLUDE(${VTK_USE_FILE})

ADD_EXECUTABLE(ens2vtk ens2vtk.cxx getpot.h) TARGET_LINK_LIBRARIES(ens2vtk
vtkIO)
//--------------------------------------------------

This CMakeLists.txt was copied from that Tutorial directory since the
program that I'm trying to compile is very very simple (just convert an
Ensight file in a VTK XML based one). On Windows systems the CMakeLists file
above works perfectly but on Unix systems I get the error message:

OK, VTK_DIR is pointing to the correct place, so I thought CMake would be
able to realize that vtkGenericEnsightReader.h IS a VTK include and set the
paths correctly.

I already tried to put a INCLUDE_DIRECTORIES(${VTK_INCLUDE_DIR}) but It
won't work either. What could be happening?

Thanks in advance

Renato.
