Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

NOTE: MUST USE GNU compliant version of sed
Run the following shell code (Adopted from Brad King scripts for CMake):

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed \
&& git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' \
   | xargs sed -i -f convert.sed \
&& rm convert.sed


This has been adapted from ITK commit e52dbe7fa476f6283c9b9d1507fca052355113a4

This modification is based according to
the process described in ITK/Utilities/Maintenance/HowToCreateTheCMakeCaseConversion.txt

COMP: Add OTB_IO_UTILITIES_DEPENDENT_LIBRARIES variable in the TARGET_LINK_LIBRARIES() command for Examples exe which have a link problem (with lib static).

Modif cmakelist par rapport au Testing : OPTION(BUILD_TESTING ..) est supprimé du CMakeListst de l'OTB (doublon avec celui présent dans Dart.cmake inclue dans cmake root).
Suppression de l'option BUILDING_EXAMPLES_TESTING.

INCLUDE_DIRECTORIES("${OTBTesting_BINARY}") : car variable non defini et sort en erreur avec cmake 2.6.0.

- MAJ 2.2.1
- Find OpenGL : correction pour trouver GLU.h. O nutilise OPENGL_GLU_FOUND
- séparation des Testing : BUIL_TESTING et BUILD_EXAMPLES_TESTING. BUT:  offrir la possibilités aux utilisateurs de tester les exemples de l'OTB (san spour autant compile rle sTesting qu'il ne peuvent aussi bien pas téster car il n'ont pas OTB-Data.
