 Use \c emsdk to install specific \c emscripten versions. For example, to install
 it for Qt 5.13, enter:
 \list
-    \li ./emsdk install sdk-1.38.27-64bit
-    \li ./emsdk activate --embedded sdk-1.38.27-64bit
+    \li ./emsdk install sdk-fastcomp-1.38.27-64bit
+    \li ./emsdk activate --embedded sdk-fastcomp-1.38.27-64bit
