 ### Standard C++ Compilation
 
-You will need to compile first the Core library before compiling the CPU one.
+You will need to compile and install the [Core Library](https://gitlab.eclipse.org/eclipse/aidge/aidge_core) before compiling the CPU one.
+
+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)
+
+make all
+```
