REM Build Doxygen documentation for every module (see cmake\Documentation.cmake)
REM and print the path to the landing page. A no-op with a clear message if
REM Doxygen isn't installed or ENABLE_DOXYGEN=OFF.
REM
REM Output goes to out\docs\ (DOCS_OUTPUT_DIR in Configuration.cmake) --
REM note this is a sibling of out\build, not nested inside it. If you've
REM overridden DOCS_OUTPUT_DIR at configure time, also set DOCS_DIR here to
REM match so the printed path is correct (docs still land in the right
REM place either way -- this only affects the message below).
REM
REM Usage (from the project root):
REM   scripts\docs.bat              REM every module
REM   scripts\docs.bat core_lib      REM just one module's docs (docs_<target>)
