Hi
I'm trying to compile a main program (it contains MPI functions) using cmake. I
get an executable file (there aren't problems in compilation ), but it doesn't
run correctly.
If I compile my code using a simple Makefile, it works; but I need to compile
it using cmake (that's a prerequisite for my work).
I have installed MPICH2 and cmake 2.8.4. and I use the next files:
CMakeLists.txt:
cmake_minimum_required(VERSION 2.7)
set(CMAKE_CXX_COMPILER "/home/lola/Packages/mpich2-1.3.2p1/bin/mpicxx")
set(CMAKE_C_COMPILER "/home/lola/Packages/mpich2-1.3.2p1/bin/mpicc")
project( ITK_MPI )
find_package ( MPI )
if ( MPI_FOUND )
include_directories( ${MPI_INCLUDE_PATH} )
endif( MPI_FOUND )
------------------------------------------------------------------------------------------------------
CMakeCache.txt:

¿What's am I doing wrong?, ¿Is there any other configuration?. I really need to
make it work.
Thank you
Lola
