The minimum CMake version for Qt6 is 3.16, so all the calls to
cmake_minimum_required() are updated here to enforce that
minimum. This will avoid any CMake version-related warnings
from Qt.
Avoid hard-coding Qt5 where the tests could now be using
Qt5 or Qt6.

Revert commit e5ec0e52f4 (AUTOUIC: Fix generating of dependency rules
for UI header files, 2021-07-22, v3.21.1~8^2) because it caused
regressions. For example, changing one C++ source can now cause many
others to rebuild. Revert the change pending further investigation.

We could not rely on .ui files when generating the ninja rules
for the generated UI header files. .ui files might be added to the
target sources but never processed by AUTOUIC afterward, since UI
header files are never included in a source code. Instead of adding
dependency rules based on the .ui files, this approach scans
non-generated source files for includes of the UI header files,
as AUTOUIC does. This gives the consistent set of UI header files
at configure time, that could be used to generate byproducts rules
for the AUTOUIC. Also, the path to the generated UI header file depends
not on the .ui file location but on the include line is used in source
files.

5b0ea5874a AutoGen: Retrieve Qt version from moc as fallback

Consider the case where the find_package call for QtCore is wrapped in a
function call. Then AutoGen cannot determine the Qt version, because it
only looks at variables and directory properties. The former don't leave
the function scope and the latter are not set by default.
As a fallback, locate the moc executable via its target and call it with
the --version argument to determine the Qt version.

Since commit f65f20938c (Autogen: Avoid processing CSharp targets,
2020-11-12, v3.20.0-rc1~301^2) we collect all sources for a target
earlier than previously. Clear the sources cache so that it will be
re-computed later after AUTOGEN processing.

The '<user target>_autogen/timestamp' target supposed to
generate ui header files using the 'uic'. Ninja must have
information about these header files as a result of generating.
The fix collects .ui files of the user target and generates
a list of the ui headers that need to be added to the generating
results of the '<user target>_autogen/timestamp' target.
The case when the .ui files are not specified and collected by
AUTOUIC from the include directives of the project source files
is not covered in this patch.

Extend Qt(4|5)Autogen.RerunMocBasic to check the following situation:
Class MyObject3 is a QObject-derived class without Q_OBJECT macro.
It's declared in myobject3.h that is not included by any file that is
input of AutoMoc (this is why we had to add PlainObject).
If myobject3.h were included by main.cpp, then AutoMoc would already
track this dependency, because main.cpp has a Q_OBJECT macro.
After the initial build(s), the Q_OBJECT macro is added to myobject3.h,
and an incremental build is run. With Qt >= 5.15 and Ninja, the build
fails, because AutoMoc is not run due to the missing dependency to
myobject3.h.
|

|
|
|

Test that removing / adding a Q_OBJECT macro doesn't break incremental
builds.
This was initially done to test the fix for #21620, but the test passes
without the fix. The reason is that test1.h is included by main.cpp, which
contains a Q_OBJECT macro, meaning that test1.h is in AutoMoc's
dependencies transitively.
|

|
|
|
|

In a subsequent patch we want to extend RerunMocBasic to test the
removal and addition of Q_OBJECT macros works when building
incrementally.
For that, properly generated dependencies are necessary. Currently, the
MocBasic test project is configured using try_compile, and that turns
off the generation of depfiles.
Replace the try_compile call with execute_command calls that first
configure and then build the test project.

This test case enables AUTOMOC on the same sources in two separate targets.
This causes the `moc_*.cpp` generation custom commands to be added to multiple
`_autogen` targets, which is not allowed by the Xcode "new build system".
Skip the part of the test that triggers this problem for now.

AutoMoc uses the moc-emitted dependency file of Qt 5.15 to track
dependencies. Such a dependency may well live outside the project and
can vanish, for example when installing a new compiler version.
This situation was detected before, but merely a warning was issued.
Now, we're considering a generated file as out of date if a dependency
is missing and re-generate it.
We also have to remove the missing dependency from the ParseCache.
Otherwise the AUTOMOC target for all generators other than Ninja will
always be out of date.
The ParseCacheChanged flag had to be made atomic, because we're
potentially accessing it from multiple threads. The dependencies vector
itself is not vulnerable in this regard, because there's one vector per
file, and we're accessing exactly one ParseCacheT::FileHandleT per thread.

For Qt >= 5.15.0 and Ninja generators AutoMoc creates a depfile to let
Ninja decide when to run AutoMoc. This was introduced by commit aebfbcaa46
(AutoGen: Use depfiles for the XXX_autogen ninja targets, 2020-01-14,
v3.17.0-rc1~58^2).
However, AutoMoc was not triggered after adding a new moc-able file to
the project. This patch adds the project file (and potentially included
files) to the dependencies in the depfile.
Now, a re-run of AutoMoc is triggered if the project file changes.

Change the default value of `CMAKE_AUTOMOC_PATH_PREFIX` to `OFF` to
restore compatibility with behavior of CMake 3.15 and below.
C++ source files that are generated by Qt's meta object compiler (moc)
include the header file that was passed as input argument to moc. This
is usually a path relative to the source directory, for example
#include "../../source/dir/myobject.h"
That is problematic for reproducible builds as described in #18815.
To cope with that, the target property AUTOMOC_PATH_PREFIX was
introduced in CMake 3.16 by commit d018d27c10 (Autogen: Add moc path
prefix generation (AUTOMOC_PATH_PREFIX), 2019-09-13, v3.16.0-rc1~94^2~4).
The property is default-initialized from the variable
`CMAKE_AUTOMOC_PATH_PREFIX`, which defaults to `ON`.
If this property is ON, and myobject.h is located in an include
directory of the target, moc-generated C++ files include the file
without the "path prefix":
#include "myobject.h"
This behavior, however, can break projects that have equally named
header files in different include directories. As "not breaking
existing projects" trumps "have reproducible builds by default" we
change the default of `CMAKE_AUTOMOC_PATH_PREFIX` to `OFF`.
Also, it is now possible to pass `-DCMAKE_AUTOMOC_PATH_PREFIX=ON` on the
CMake command line. Before, it was overridden in `CMakeGenericSystem`.

In Qt version 5.15.0 moc learned to output the dependencies
of the generated file.
This commit enhances JobCompileMocT to read the dependency file
written by moc. The dependencies are stored in the same cache that's
used for the dependencies determined by dependency filters.
The dependency filter functionality is turned off if moc's dependency
output feature is used.

Add a test for policy CMP0100 that configures whether or not
AUTOMOC and AUTOUIC should process .hh header files.

In commit 7fa7f55230fda5ac0135b1f4a220c15ad5983857, the Autogen/SameName test
was changed to not test .hh header file processing in AUTOGEN anymore,
because we had to revert that feature. Since we now support .hh header file
processing in AUTOMOC again, we can restore the Autogen/SameName test for
that.

Since commit 4a9154537c (Autogen: Use cmake::IsHeader/SourceExtension

`.hh` files with `AUTOMOC`. However, this change can break existing
projects that do not expect the behavior. Revert it for now. It can
be restored later via a policy.

Since commit 5990ecb741 (Compute implicit include directories from
compiler output, 2018-12-07) we now have compiler implicit include
directory computation for gcc and clang. It should be safe now to pass
these to `moc`. This patch re-enables passing the compiler implicit
include directories to `moc`, which was disabled due to issue #18669.

Adds a Qt core only test that has ``AUTOUIC`` enabled
targets that don't link against QtXWidgets or Qt at all.

some require the Qt gui libraries to function.
This replaces the AutogenTest.cmake script with two specific
AutogenCoreTest.cmake and AutogenGuiTest.cmake scripts that
are included on demand.
