# building Qt from source.

Make standalone tests build via top level repo project Previously repo/tests/CMakeLists.txt was a standalone project on which CMake could be called. This was useful for Coin to be able to build and package only tests, but was a bit troublesome because that means having to specify the usual boilerplate like minimum CMake version, which packages to find in every tests.pro project. Instead of having a separate standalone project, modify the top level project and associated CMake code to allow passing a special QT_BUILD_STANDALONE_TESTS variable, which causes the top level project to build only tests, and find Qt in the previously installed qt location. This also means that when building a repo, we generate a ${repo_name}TestsConfig.cmake file which does find_package on all the modules that have been built as part of that repo. So that when standalone tests bare built for that repo, the modules are automatically found. qt_set_up_standalone_tests_build() is modified to be a no-op because it is not needed anymore. Its usage should be removed from all the other repos, and then removed from qtbase. Non-adjusted tests/CMakeLists.txt projects in other repositories should still be buildable with the current code, until they are updated to the new format. Adjust the Coin build instructions to build the standalone tests in a separate directory. Adjust pro2cmake to generate new structure for the tests/tests.pro projects. Adjust the qtbase tests project.

Make toolchain inspection more robust QtAutoDetect.cmake did read the (possibly detected) toolchain file and looked for the string "The Android Open Source Project" to deduce that we want to build for Android. This has been done, because we're autodetecting the platform before the first project comment, i.e. before the toolchain file is loaded. This magic string detection is a bit fragile, and we need a similar approach for WebAssembly. A more robust approach would be to fetch the value of CMAKE_SYSTEM_NAME from the toolchain file without actually loading it. Now, we run a CMake script that includes the toolchain file and prints variables were interested in. The calling code reads these variables and stores them in prefixed variables in the current scope.

CMake: Autodetect Android toolchain file and NDK The Android toolchain file is now autodetected from the location of the NDK. The NDK location can be specified by setting the CMake variable ANDROID_NDK_ROOT. Auto-detection of the Android toolchain file is the only purpose of this variable. In recent Android SDK installations the path to the NDK is well-known and can be auto-detected too. If only ANDROID_SDK_ROOT is given, we try to detect ANDROID_NDK_ROOT first and from that the Android toolchain file. Adjust the build instructions in cmake/README.md, and remove the part where we suggest to set some environment variables that are only used to create the cmake call.

CMake: Handle automatic rpath embedding correctly Instead of using CMAKE_INSTALL_RPATH to embed an absolute path to prefix/libdir into all targets, use the more sophisticated aproach that qmake does. For certain targets (modules, plugins, tools) use relative rpaths. Otherwise embed absolute paths (examples, regular binaries). Installed tests currently have no rpaths. On certain platforms rpaths are not used (Windows, Android, iOS / uikit). Frameworks, app bundles and shallow bundles should also be handled correctly. Additional rpaths can be provided via QT_EXTRA_RPATHS variable (similar to the -R option that configure takes). Automatic embedding can be disabled either via QT_FEATURE_rpath=OFF or QT_DISABLE_RPATH=ON. Note that installed examples are not relocatable at the moment (due to always having an absolute path rpath), so this is a missing feature compared to qmake. This is due to missing information on where examples will be installed, so a relative rpath can not be computed. By default a Qt installation is relocatable, so there is no need to pass -DQT_EXTRA_RPATHS=. like Coin used to do with qmake e.g. -R . Relative rpaths will have the appropriate 'relative base' prefixed to them (e.g $ORIGIN on linux and @loader_path on darwin platforms). There is currently no support for other platforms that might have a different 'relative base' than the ones mentioned above. Any extra rpaths are saved to BuildInternalsExtra which are re-used when building other repositories. configurejson2cmake modified to include correct conditions for the rpath feature. It's very likely that we will need a new qt_add_internal_app() function for gui apps that are to be installed to prefix/bin. For example for Assistant from qttools. Currently such apps use qt_add_executable(). The distinction is necessary to make sure that relative rpaths are embedded into apps, but not executables (which tests are part of).

CMake: Protect against Qt toolchain file recursive inclusion Three different people have encountered the issue that calling calling qt-cmake on a project prints 1000 inclusion lines of the same qt toolchain file, and then CMake bails out saying can't find the CMAKE_MAKE_PROGRAM Ninja. This happened because people accidentally called qt-cmake to configure qtbase (instead of just cmake), which created a toolchain file that chainloads itself recursively. Error out when configuring qtbase, and when using the generated toolchain file in the case when it would try to include itself. The solution is to remove the qtbase CMakeCache.txt file, and configure qtbase again, so it generates a proper qt.toolchain.cmake file. If somebody feels enthusiastic, they can move the check into the qt-cmake and qt-cmake-private shell scripts, and error out before the qtbase/CMakeCache.txt is polluted with the wrong toolchain file. That is left for people that feel more comfortable with bash and batch scripting. Change-Id: If518c94791fe7c30731e6e462e347f26a5213c64 Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>

qt_auto_detect_darwin()
Add initial support for cross-building to iOS Tested locally with the following configurations: - iOS device builds (arm64) - iOS simulator builds (x86_64) - iOS simulator_and_device builds (fat arm64 and x86_64 archives) All iOS builds currently require a custom vcpkg fork which contains fixes for building the required 3rd party libraries. qtsvg, qtdeclarative, qtgraphicaleffects and qtquickcontrols2 have also been tested to build successfully. simulator_and_device builds are also supported, but require an umerged patch in upstream CMake as well as further patches to vcpkg.

qt_auto_detect_ios()
Add auto detection routines for android Add QtAutoDectect cmake which has routines to handle the vcpkg detection as well as set up some android configuration parameters. The latter will contribute towards keeping the cmake configuration commands shorter when targeting android.

qt_auto_detect_vpckg()
CMake: Fix auto-detection of precompiled header support PCH files were only used while building qtbase. Make sure the value is exported to the BuildInternalsConfig file, so the value is re-used when building other repositories. Also disable PCH when building simulator_and_device iOS builds, because CMake doesn't currently generate separate PCH files per architecture.
