In the case of re-doing, `configure` and `configure.bat` pass an extra
parameter to the `QtProcessConfigureArgs.cmake`. As a result, CMake
removes CMakeCache.txt and CMakeFiles/ before the reconfiguration. If
the user is using CMake 3.24 or newer, this is achieved by passing
the `--fresh` option to CMake call. In older CMake(s), CMakeCache.txt
and CMakeFiles/ found in CMAKE_BINARY_DIR will be removed using a

[ChangeLog] The -redo option now additionally removes existing
CMakeCache.txt file, and CMakeFiles/ directory, and recreates them from

Instead of constantly trying to find packages by calling
qt_find_package on each reconfiguration, record which packages were
found during initial configuration. Then on a second reconfiguration,
skip looking for packages that were not found on the initial
configuration.
This speeds up reconfiguration on certain platforms and repos.
Here are some stats for my macOS qtbase build.

not skip 15.03s user 10.58s system 97% cpu 26.334 total
skip 13.87s user 5.16s system 96% cpu 19.724 total
Note this is a behavior change from how find_package is used in most
CMake projects, where if a package was previously missing, the
developer can just install the package and reconfigure to pick it up.
With this change, they will first have to remove their CMakeCache.txt
file and configure from scratch, or remove the
QT_INTERNAL_PREVIOUSLY_FOUND_PACKAGES cache variable and reconfigure.
For this reason, we enable this behavior by default only in
-developer-builds.
Builders can also opt in or out by setting the
QT_INTERNAL_SAVE_PREVIOUSLY_FOUND_PACKAGES variable to either ON or
OFF.
Note this behavior does not apply to user projects, or direct
find_package calls (as opposed to qt_find_package).

CMake has logic to rewrite build rpaths that contain
CMAKE_STAGING_PREFIX to instead point to CMAKE_INSTALL_PREFIX.
This breaks running executables from the build directory, because
their build rpath will point to a location where the libraries might
not exist yet (we didn't install Qt yet).
Work around this by setting CMAKE_STAGING_PREFIX to a fake path, so
that CMake does not do the rewriting anymore.
CMAKE_STAGING_PREFIX needs to be set at subdirectory scope, not
function scope, which is why
qt_internal_apply_staging_prefix_build_rpath_workaround() is a macro
that is called from within each Qt internal function that creates
a target.
The workaround can be disabled by configuring with
-DQT_NO_STAGING_PREFIX_BUILD_RPATH_WORKAROUND=ON
The downside of this workaround is that it breaks per-subdirectory
install rules like 'ninja src/gui/install'.
Regular global installation like 'ninja install' works fine.
This is similar to what we do for tests in
qt_set_up_fake_standalone_tests_install_prefix()
introduced by 20292250d4
The reason it's not as good for other target types is because in
contrast to tests, we do want to install them.
In case if someone does call `ninja src/gui/install' they will most
likely get a permission error, telling them it's not possible to
install into

Aka handle CMAKE_INSTALL_PREFIX in a more relocatable way.
The following story inspired this change.
If a user wants to build a Qt repo into a different install prefix
than the usual Qt one, this will fail configuration because we
look for various things like syncqt, qdoc, etc relative to
CMAKE_INSTALL_PREFIX, which will now point to a different location
where none of the above tools are located.
The intent for such a use case is to support building Qt packages with
Conan, which sets a random install prefix when configuring a repo.
The idea is to derive the qt prefix dynamically from the
QtBuildInternals package location. Essentially it's a reverse relative
path from the QtBuildInternalsConfig.cmake file to the install prefix
that was specified when initially configuring qtbase.
Once the dynamic prefix is computed (so we know where the possibly
relocated Qt is), we can find tools like syncqt and qdoc.
This is an initial attempt to support a use case like that.
More design work will probably needed in case if tools / libs need to
be found in a location different than the Qt install prefix (so
support for multiple install prefixes / search paths).
An example of such a case would be when building qtdeclarative and
qtquickcontrols2 as Conan packages in one go. Most likely the
qmltyperegistrar tool will be located in the random install prefix
set by Conan, so building qtquickcontrols2 might fail due to not
finding the tool in the original Qt install prefix.
As to the implementation details, the change does the following:
- Dynamically computes and sets the
QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX variable when
find_package()'ing QtBuildInternals. It's an absolute path
pointing to where the relocated Qt is.
- When building qtbase this variable is not yet available (due
to QtBuildInternalsExtra not existing), in that case we set
the variable to the absolute path of CMAKE_INSTALL_PREFIX
(but only for the initial qtbase configuration).
- Remove QT_BUILD_INTERNALS_ORIGINAL_INSTALL_PREFIX which was used
for standalone tests purposes. It's not needed now that we compute
the location of the Qt prefix dynamically.
- The Unixy qt-cmake and qt-cmake-private shell scripts now
use a relative path to find the toolchain file we created.
- The toolchain file also dynamically computes the location of the Qt
packages, and adds them to CMAKE_PREFIX_PATH.
- A lot of existing CMAKE_INSTALL_PREFIX uses are replaced with
QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX. This includes finding
tool locations, mkspecs dir, path environment setup for tools, etc.
- Some places still use CMAKE_PREFIX_PATH in the following cases
- When determining paths while configuring qtbase (valid cases)
- When I wasn't sure what the behavior should be, so I left them
as-is (an example is documentation generation, do we want to
install it into the random Conan prefix, or into the main prefix?
Currently it installs in the random prefix).
Note that relocating a Qt installation does not work for non-prefix /
non-installed builds, due to hardcoded paths to include directories
and libraries in generated FooTargets.cmake files.

This is needed, to ensure that all features are evaluated by the

Some report and summary entries are not generated if they mention a
