Subject: [PATCH] Add clang-format target to cmake
If `clang-format` is found the 'clang-format' target is defined. To build this
target, clang format is run on pastis sources (c++) omitting 'packages' sources.
It is better to configure editors to use clang-format than running this on the
whole sources before pushing...
