+absolute_paths
+^^^^^^^^^^^^^^
+
+By default, ``CMakeToolchain`` will generate relative paths. For example the ``CMakeUserPresets.json`` will have a
+relative path to the included ``CMakePresets.json`` (both files generated by ``CMakeToolchain``), and the 
+``CMakePresets.json`` file will have a relative path to the ``conan_toolchain.cmake`` file defined in its ``toolchainFile``
+field, that will be relative to the build folder, as specified by the CMake presets documentation.
+
+If for some reason using absolute paths was desired, it is possible to do it with:
+
+.. code:: python
+
+    def generate(self):
+        tc = CMakeToolchain(self)
+        tc.absolute_paths = True
+        tc.generate()
