Add automatic uic invocation for Qt.

The source files are already processed by cmQtAutomoc to look for
moc includes, so extend that to also look for ui_ includes and
find corresponding .ui files to process.

This replaces the need to invoke qt4_wrap_ui().

As the ui files are not likely to be part of the SOURCES of the
target, store the options associated with them separately in the
cmMakefile for querying during the autogen run.

+AUTOUIC
+-------
+
+Should the target be processed with autouic (for Qt projects).
+
+AUTOUIC is a boolean specifying whether CMake will handle
+the Qt uic code generator automatically, i.e. without having to use
+the QT4_WRAP_UI() or QT5_WRAP_UI() macro. Currently Qt4 and Qt5 are
+supported.
+
+When this property is set to TRUE, CMake will scan the source files
+at build time and invoke uic accordingly.
+If an #include statement like #include "ui_foo.h" is found in
+foo.cpp, a foo.ui file is expected next to foo.cpp, and uic is
+run on the foo.ui file.
+This property is initialized by the value of the :variable:`CMAKE_AUTOUIC`
+variable if it is set when a target is created.
+
+Additional command line options for uic can be set via the
+:prop_sf:`AUTOUIC_OPTIONS` source file property on the foo.ui file.
+The global property :prop_gbl:`AUTOGEN_TARGETS_FOLDER` can be used to group the
+autouic targets together in an IDE, e.g. in MSVS.

+AUTOUIC_OPTIONS
+---------------
+
+Additional options for uic when using autouic (see the :prop_tgt:`AUTOUIC` target property)
+
+This property holds additional command line options
+which will be used when uic is executed during the build via autouic,
+i.e. it is equivalent to the optional OPTIONS argument of the
+qt4_wrap_ui() macro.
+
+By default it is empty.
+
+This property is initialized by the value of the variable
+:variable:`CMAKE_AUTOUIC` if it is set when a target is created.
+
+The options set on the target may be overridden by :prop_sf:`AUTOUIC_OPTIONS` set
+on the .ui source file.
