522c7ba1ac Enable bundling Qt in Android package in build system
For bundling Qt, we need two things:

1. We need to build a regular .jar file out of the Java files,
so that they can be built into the app package. Dexing the
classes first (i.e. compiling the JVM bytecode to Dalvik
bytecode) is required for loading the .jar file at run-time,
but cannot be used for building it into the app, so we need
two different paths.

2. We need to specify which extra files have to be bundled for
each module (this is primarily for plugins and imports). This
is because there is no static dependency on these files, so
it cannot be detected during deployment.

f1fd824ebb make src/ subdir optional
there is at least one examples-only repo (qtwebkit-examples).

we look for tools/ only when src/ is also present, based on the
assumption that if there was only tools/, it would be actually named
src/ (like in qttools). the split between the two is nowadays arbitrary
anyway.

fda41c1857 groundwork for making "configure -nomake tools" sane
the idea is that "tools" actually means "graphical applications". that
means that all bootstrapped/build tools are consistently built,
regardless of their location in the source tree.
non-bootstrapped non-graphical tools are a bit of a grey area. it's
going to be decided on a case-by-case basis.

bc4fbcd215 Add IMPORTED targets for the GL libraries used by Qt.
There may be multiple libraries specified in the mkspec, such as
EGL and Mali, as used in devices/linux-sh4-stmicro-ST7108-g++, so
create an imported target for each one. Also populate the
Qt5Gui_EGL_LIBS variable with all created imported targets. Similar
variables are created for the used OPENGL implementation.

In the case of using the packaged ANGLE library, we already know the
exact locations of the binaries.

This makes it possible for third parties to use the same GL
implementation as used by the Qt build itself. As these are used only
privately by QtGui, they are also added to the DEPENDENT_LIBRARIES
of that target so that they are found for rpath-link usage.

On some platforms (eg Raspberry Pi), multiple include directories must
be set to include egl.h, as the headers it includes for vcos are a
bit scattered.

a680fe609f Add the GL headers to cmake variables.
If building angle ourselves, that's just the basic Qt include dir,
and if using an external gl, look for it in the places specified
in the mkspec.

As the qopengl.h header includes the gl header, this is a 'public
include dependency' of QtGui, so it is added to the relevant
variable and the INTERFACE_INCLUDE_DIRECTORIES of Qt5::Gui.

5aa349628e Handle usr-move without forcing absolute paths
In qtbase commit 7ac58d1ff0 (Make cmake
packages installed to /usr non-relocatable., 2013-02-11), we made
cmake config files non-relocatable if they were installed to
the /usr prefix. That was assumed to mean that this was a distro
or platform package, and was a workaround for the usr-move problem
on Fedora and ArchLinux.

However, cmake bug http://public.kitware.com/Bug/view.php?id=14041
showed that forcing absolute paths in this situation is not desirable
in cross compiling scenarios. CMake commit 6c613b433c45efb0bb013a6bd668cbb8ac740259
(Handle usr-move without forcing absolute paths (#14041), 2013-04-03)
addressed the problem in CMake, and this commit is an equivalent.

For iOS the deployment target has to be bumped from 4.3 to 5.0, but we
don't enable C++11 by default yet as it's not tested enough on iOS.

Users who wish to deploy to 10.6 need to build their own Qt,
passing -no-c++11 to configure.

898e701b4a bring bootstrapped QT magic from qt_tool to qt_module
project files of bootstrapped modules can, just like those of
bootstrapped tools, benefit from automatic adjustment of QT (and
CONFIG).

1b00363b2f fix replacement base path
this affects only webkit when doing module-by-module installation, so it
went unnoticed.

a5d09b9036 enumerate modules in QT_MODULES, not QT_CONFIG
QT_CONFIG is supposed to contain configure output, not a list of
modules. for example, enumerating modules is not cleanly possible if
modules are mixed with other flags.

the conflation was merely historical, due to webkit and phonon doing
it this way in the preliminary qt4 modularization.

we now have a much cleaner way to query modules (qtHaveModule(<module>),
or less recently, !isEmpty(QT.<module>.name)), which is already used
throughout Qt.

the old way was supposed to be removed for 5.0 already, but it slipped.
better do it now, before people actually start using it.
