Subject: Allow ecm_create_qm_loader() to be passed the _SRCS variable

This allows a more straightforward way of using it, which matches the
macros that generate things like D-Bus interfaces.

 # ecm_create_qm_loader() generates a C++ file which ensures translations are
-# automatically loaded at startup. The path of the .cpp file is stored in
-# <source_file_var>. This variable must be added to the list of sources to
-# build. For example this call:
+# automatically loaded at startup. The path of the .cpp file is appended to
+# <source_files_var>.  Typical usage is like:
 #
 # .. code-block:: cmake
 #
-#   ecm_create_qm_loader(qmloader mylib)
-#
-# generates a C++ file which loads "mylib.qm" at startup, assuming it has been
-# installed by ecm_create_qm_from_po_files(). The name of the C++ file is
-# stored in the ``${qmloader}`` CMake variable. This variable must be integrated
-# in the list of source files for the library:
-#
-# .. code-block:: cmake
-#
-#   set(mylib_SRCS foo.cpp bar.cpp ${qmloader})
+#   set(mylib_SRCS foo.cpp bar.cpp)
+#   ecm_create_qm_loader(mylib_SRCS mylib)
 #   add_library(mylib ${mylib_SRCS})
+#
+# This generates a C++ file which loads "mylib.qm" at startup, assuming it has
+# been installed by ecm_create_qm_from_po_files(), and compiles it into ``mylib``.
