+Store in a Cython module if it was compiled with OpenMP
+
+You have to patch the setup module like that:
+
+.. code-block:: python
+
+    silx_include = os.path.join(top_path, "silx", "utils", "include")
+    config.add_extension('my_extension',
+                         include_dirs=[silx_include],
+                         ...)
+
+Then you can include it like that in your Cython module:
+
+.. code-block:: python
+
+    include "../../utils/_have_openmp.pxi"
