-- TODO
+- cuda 11 ( >= 11.6, preferably the latest cuda 11 version available). There is a known bug on cuda 11.4 (issue #302).
+- Eigen 3.4.x.
+- [matio](https://github.com/tbeu/matio) version >= 1.5.7 (guaranteed) and <= 1.5.17 (potentially), and its own dependencies, as hdf5. This dependency can be disabled through cmake option ``NO_MATIO``.
+- Python3 (with numpy, scipy and cython) to build the python wrappers.
+- MATLAB (>= R2017b) to build the matlab wrappers.
+- libxml2 (Optional, needed with CMake ``BUILD_READ_XML_FILE``).
+- TODO: other?

 **Warning 2**:
 Many CMake build options are available (cf. [CMakeLists.txt](./CMakeLists.txt)). It might be quite complicated to deal with them at start (refer to gitlab ci building scripts in [./misc/continuous\_integration/jobs/](./misc/continuous_integration/jobs/) or the [.gitlab-ci.yml](.gitlab-ci.yml) root script to get some insight).
