+CMake projects may be integrated in various IDEs.
+
+Some IDEs sport a CMake plug-in, notably VScode.
+This is the easy case -- please refer to the documentation of the relevant plug-in.
+
+Unfortunately, ST's Cube IDE does not have such a plug-in. A procedure to handle CMake projects nonetheless,
+using its built-in support for Makefiles, is detailed below.
+
+# Requirements
+
+The same requirements as detailed in the [[Setup]] page for shell users apply.
+
+# Walkthrough
+
+The first step is to create or import a __"Makefile Project with Existing Code"__:
+
+![1](./img/cmake_cubeIDE/1.png)
+
+-----------------
+
+Then browse for the project's location, and leave all other settings to default as illustrated below:
+
+![2](./img/cmake_cubeIDE/2.png)
+
+-----------------
+
+The next step is to fill in the build settings.
+Right click on the project, hit "Properties" (or `Alt`+`Enter`), then go to the "C/C++ build" section.
+Fill in the "Builder Settings" and "Behavior" tabs as follows
+(be sure to replace the build location with the relevant value for your project).

+
+You may also change the build command to "ninja"; this is known to be much more efficient, in terms of build time, than Make.
+
+-----------------
+
+Once this is done, there remains to tell CubeIDE how to run CMake.
+Right click on the project, hit "Build targets" -> "Create" (or `Shift`+`F9`, "Add").
+

+
+Fill the window that pops up as follows:
+
+![6](./img/cmake_cubeIDE/6.png)
+
+Build command :
+```sh
+# if you stuck with Make in the previous step
+cmake -S [source folder] -B [build folder] -G Unix\ Makefiles
+
+# or, if you picked Ninja earlier,
+cmake -S [source folder] -B [build folder] -G Ninja
+```
+
+For the source and build folder, you can use one of Cube's automatic variables, such as `${workspace_loc:/1_Blink}/build`, as in the project settings.
+Make sure the build folder (`-B`) matches the value you passed in the project build configuration step!
+
+-----------------
+
+Now, all the configuration steps are done.
+
+To run CMake, build the target you created in the previous step (or hit `F9`):

+
+To or rebuild the project, hit `Ctrl`+`B`, or right-click on the project -> "Build project".
