[CMake] CHECK_INCLUDE_FILES

[Nico Schlömer]

Hi,

I'd like to find out whether the file /usr/include/vtk-5.8/vtkMPI.h is
present on the system. I found CHECK_INCLUDE_FILES, and tried to use
it like

================ *snip* ================
cmake_minimum_required(VERSION 2.8)
INCLUDE(CheckIncludeFiles)

SET(CMAKE_REQUIRED_INCLUDES /usr/include/vtk-5.8)
CHECK_INCLUDE_FILES(vtkMPI.h TEST)

MESSAGE("<<${TEST}>>")
================ *snap* ================

However, this doesn't seem to work return TRUE even if the file is present.
Any idea what I'm doing wrong?
