 ### Standard C++ Compilation
 
-You will need to compile first the Core library before compiling the CPU one.
-The makefile is designed to do it for you.
+You will need to compile and install the [Core Library](https://gitlab.eclipse.org/eclipse/aidge/aidge_core) before compiling the CPU one.
 
-To only compile the CPU library, run
-```
-make cpu_only
-```
+Once this has been done, you'll need run CMake with the
+`CMAKE_INSTALL_PREFIX:PATH` flag, in order to indicate to CMake where
+`aidge_core` has been installed : 
+```sh
+cmake -DCMAKE_INSTALL_PREFIX:PATH=$(path_to_install_folder) $(CMAKE PARAMETERS) $(projet_root)
 
-To compile the CPU library + the associated unitary tests, run
-```
-make cpu_tests
+make all
 ```
 
-To compile the CPU library with the python binding, run
-```
-make cpu_with_pybind
-```
-Important: this command can also be run with `make`.
