+---------
+
+The Emscripten platform doesn't support the use of shared libraries as known by cmake.

+
+This workaround only works due to the way the cmake scripts are loaded.
+
+Prior to the use of ``project( ... )`` directive we need to set
+``CMAKE_PROJECT_INCLUDE=cmake/emscripten.cmake``.
+This file will be loaded after the toolchain overriding the settings that
+prevent shared library building.
+
+CMAKE_PROJECT_INCLUDE was Added in version 3.15.
+``CMAKE_PROJECT_<projectName>_INCLUDE`` was Added in version 3.17:
