+#[=======================================================================[.txt:
+  Adds VSTGUI support.
+  
+  Usage:
+    smtg_enable_vstgui_support(VSTGUI_SOURCE_DIR "<path-to-the-vstgui-source-folder>")
+
+  Exports:
+    smtg_enable_vstgui_support exports "<path-to-the-vstgui-source-folder>" 
+    as SMTG_VSTGUI_SOURCE_DIR to its parent scope.
+
+  Deprecation:
+    The usage wihout parameters is depricated.
+    SMTG_VSTGUI_ROOT is exported for compatibility reasons and is also depricated.
+    Replace "${SMTG_VSTGUI_ROOT}/vstgui4" with "${SMTG_VSTGUI_SOURCE_DIR}".
+    The export of "${SMTG_VSTGUI_ROOT}" may be removed in future SDK versions.
