- create config files to store definitions
 - include/chameleon_config.h: definitions exposed to the public (installed file)
 - control/config.h: additional definitions used internally
- modify source code to call the config files when it is necessary (when the different "if defined" are used)

does not build with starpu/simgrid if symbols starpu_mpi_cache_flush and starpu_mpi_cache_flush_all_data

change the way we include our own header files --> relative to the root - when plasma is in the same env, chameleon can take some headers not belonging to it (ex: #include descriptor.h, this file states in plasma install dir also) which make compilation errors

change copyright - correct whitespace - place cmake module depending on chameleon in cmake_modules and no more in cmake_modules/morse
