  - You can use `cmake -G Ninja ..` to use Ninja build system instead of the native one. (`sudo apt install ninja-build`)
- - Use `cmake --build . -j 8` or `cmake --build . -j 8 -v` instead of make (works with all build systems)
+ - Use `cmake --build . -j 8 [--target TARGET]` or `cmake --build . -j 8 -v [--target TARGET]` instead of make (works with all build systems)
  - Use `cmake --build . --target clean` or `cmake --build . --target distclean`
  - Use `ccmake ..` or `cmake-gui ..` to change config option:

-       . Debug : -g
-       . RelWithDebInfo : -O3 -g  (default)

 There is a GUI tool that can help for writing MMVII command : vMMVII
 
 It will be automatically compiled with MMVII if development package Qt5 (or Qt6) is installed (Ubuntu 22.04: `sudo apt install qtbase5-dev`)
-Windows: You may have to add path to Qt

+Windows: You may have to add Qt installation path when running cmake configuration :

 Usage: just type "vMMVII" in your working directory.
 
 - Sorry, no documentation yet

 - This tool is beta: some MMVII parameters may be misinterpreted or not have the good File Dialog helper.
