5a8555c53f CMake: Fix FindWrapRt
We must use the LIBRT location instead of LIBRT_FOUND which is not set anywhere.
I failed to replace this one in my previous patch.

062b50abff CMake: Namespace all our IMPORTED targets
CMake IMPORTED targets should be namespaced so that CMake knows that
the name refers to a target and not a file.

Use the existing WrapXXX naming scheme where applicable.

331b153be5 CMake: Fix FindWrapRt module when it's found multiple times
On Windows, when WrapRt is qt_find_pacakge()'d the first time, the
result is "not found", whereas a second time it would claim that the
package is found.

This is due to the WrapRt target being always created even if it has
no transitive dependencies, and thus a second search would check only
for the existence of the target.

Fix the module to only create the target if the relevant library
is found.

9b0b464e82 Write find_dependency() calls in Qt Module config files
This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.

This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.

For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.

The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.

The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.

Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.

In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any
scope, the targets on which the property is set, have to be GLOBAL.

Also for applications and other modules to find all required third
party libraries, we have to install all our custom Find modules, and
make sure they define INTERFACE IMPORTED libraries, and not just
IMPORTED libraries.
