+# This cmake configuration file is based on the work by Werner Volken <werner.volken@vsw.ch>
+
+# To create a native build of XaoS on Linux:
+#
+# * download a recent Qt SDK (at least Qt 6.2.4 is recommended),
+#
+# * install CMake (at least CMake 3.14 is suggested),
+#
+# * type:
+#
+#   mkdir build; cd build \
+#   CMAKE_PREFIX_PATH=<PATH_TO_QT_SDK>/Qt/6.6.1/gcc_64/lib/cmake/Qt6LinguistTools \
+#     cmake -DCMAKE_INSTALL_PREFIX=<INSTALLATION_PATH> .. && \
+#   make -j<N_PROCS>
+#
+#   where
+#   - PATH_TO_QT_SDK is the path of your Qt SDK installation (typically $HOME/Qt),
+#   - INSTALLATION_PATH is the planned installation folder of the executable and the supplementary files
+#     (typically $HOME/install/xaos),
+#   - N_PROCS is the number of processors you want to use for the compilation (if you have 8 cores,
+#     you may want to use 6).
+#
+# * If the compilation succeeds, you can directly type:
+#
+#   ./XaoS
+#
+# * To install XaoS in your INSTALLATION_PATH, type:
+#
+#   make install
+#
+# * To run XaoS from your installation path, type:
+#
+#   cd <INSTALLATION_PATH>; ./XaoS
