@@ -489,9 +489,12 @@ When the command will happen is determined by which
of the following is specified:
``PRE_BUILD``
On :ref:`Visual Studio Generators`, run before any other rules are
executed within the target.
On other generators, run just before ``PRE_LINK`` commands.
This option has unique behavior for the :ref:`Visual Studio Generators`.
When using one of the Visual Studio generators, the command will run before
any other rules are executed within the target. With all other generators,
this option behaves the same as ``PRE_LINK`` instead. Because of this,
it is recommended to avoid using ``PRE_BUILD`` except when it is known that
a Visual Studio generator is being used.
``PRE_LINK``
Run after sources have been compiled but before linking the binary
or running the librarian or archiver tool of a static library.
