Subject: [PATCH]    * All Tools:      - Change: New structure for the
 installation & CMake system.          * Tools are now grouped in "projects".
 There are three projects:            1. - IO: Standalones parsers/drivers
 (IO_USER_TOP, IO_TOP).            2. - Coriolis: Base & digital tools
 (CORIOLIS_USER_TOP, CORIOLIS_TOP).            3. - Chams: Analogic tools
 (CHAMS_USER_TOP, CHAMS_TOP).            Each *project* has a two "TOP"
 environement variables, for          example: IO_TOP and IO_USER_TOP. Thoses
 variables are the only          ones useds to locate the tool (CMake modules,
 headers & libraries).            The local path always takes precedence over
 the global one.            The localisation process occurs in each tool top
 CMakeLists.txt          where the macro SETUP_PROJECT_PATH is to be defined.
 There is no          way to put it in a shared includes file as it's the
 macro precisely          used to locates the includes... You have to call the
 macro once for          each project you wants to uses:             
 SETUP_PROJECT_PATHS(IO)              SETUP_PROJECT_PATHS(CORIOLIS)          *
 In FindTOOL.cmake, supress the <TOOL>_DIR_SEARCH and uses the         
 <PROJECT>_DIR_SEARCH instead (example: CORIOLIS_DIR_SEARCH).          *
 buildCoriolis.py modificated according to the new "TOP" scheme.
