Contributions summary:Manuel primarily focused on fixing bugs related to static const strings and linking issues when integrating with external applications, specifically the Orfeo Toolbox. They addressed these issues by modifying existing code in the ITK library, specifically within the binary morphology and watershed segmentation modules, as well as the numeric traits header. The user added the `ITKCommon_EXPORT` macro to resolve linking conflicts with applications using ITK. Their work improved the compatibility and stability of ITK, allowing for successful compilation and linking with external projects.
