* CMake: Fill QT.<module-name>.uses entries in module .pri filesJoerg Bornemann2020-11-301-0/+8
| | | | | | | | | | | | | | | | Those entries were always empty. The INTERFACE_QT_MODULE_USES property was never set. Map each public dependency to its qmake lib name and place this value into the module's QT.<module-name>.uses variable. Take into account the "_nolink" target modifier and translate it to qmake's "/nolink".

* CMake: Fix resource objects story in static prl filesAlexandru Croitor2020-11-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CMake build of Qt intends to improve the developer experience in regards to static Qt builds and Qt resource files. Specifically with a CMake build of Qt, Qt developers don't have to manually call Q_INIT_RESOURCE anymore. For details see the following commits e343affd6345ef8db041789a96016c3a84830dc9 e817ac3d68295fc0670ccede4df08bf1c7e627d2 4ab54320817ebbb465af343514d21139a654aed3 The last commit's implementation is incomplete though. To ensure successful linking, each target's prl file should contain not only the resource object files that are assigned to the target, but also all resource object files of the target's dependencies. To achieve that, qt_collect_libs will now recursively collect all resource object files assigned to the QT_RCC_OBJECTS property of each dependency. Note this implementation is still incomplete. We do not export rcc object file information in the CMake Targets files. That means that when configuring qtdeclarative in a non-top-level build, the generated Qml prl file will not contain references to Core's mimetypes resource object file, etc. So with the current change, only the object files that are part of the current CMake configuration build are tracked. Exporting the resource object files locations proves in a format usable for prl files proves to be difficult (due to CMake not supporting exporting genexes in random properties) and will have to be addressed in a separate change.

* Generalize the winmain/qtmain entry-point libraryTor Arne Vestbø2020-10-171-3/+3
| | | | | | | | | | The use-case is relevant for other platforms as well. Now that Qt has a module system we can also replace a lot of the hand crafted logic for linking with simpler constructs.

* CMake: Refactor optimization flag handling and add optimize_fullAlexandru Croitor2020-10-061-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a bunch of helper functions to manipulate compiler flags and linker flags for the CMAKE_<LANG>_FLAGS_<CONFIG> and CMAKE_<LINK_TYPE>_LINKER_FLAGS_<CONFIG> CMake variables. These variables can be assigned and modified either in the cache or for a specific subdirectory scope, which will apply the flags only to targets in that scope. Add qt_internal_add_optimize_full_flags() function which mimics qmake's CONFIG += optimize_full behavior. Calling it will force usage of the '-O3' optimization flag on supported platforms (falling back '-O2' where not supported). Use the function for the Core and Gui subdirectories, to enable full optimization for the respective Qt modules as it is done in the qmake projects. To ensure that the global qmake-like compiler flags are assigned eveywhere, qt_internal_set_up_config_optimizations_like_in_qmake() needs to be called after Qt global features like optimize_size and optimize_full are available. This means that qtbase and its standalone tests need some special handling in regards to when to call that function.

* CMake: Add facility to mark package dependencies as optionalJoerg Bornemann2020-09-121-4/+6
| | | | | | | | | | | | | | | | Every public dependency of a Qt module results in a find_package call in the consuming project. But not all public dependencies are mandatory. For example, vulkan is only needed if the user project actually uses Qt classes that pull in vulkan headers. This patch adds the option MARK_OPTIONAL to qt_find_package. Dependencies that are marked as optional will not produce an error on find failure.

* CMake: Provide way to register extra tool package dependenciesAlexandru Croitor2020-09-111-1/+39
| | | | | | | | | | | | | | | This is needed for qtwayland, where QtWaylandCompositor package should call find_package(QtWaylandScanner) in the 'Tools' section of the ModuleDependencies.cmake file, rather than the regular 'Qt' section. This takes care of handling host path prefixes, to ensure that a host package is found even when tools have also been cross-compiled via the QT_BUILD_TOOLS_WHEN_CROSSCOMPILING option.

* CMake: Split QtBuild.cmake into smaller filesAlexandru Croitor2020-08-141-0/+246
QtBuild.cmake is huge. Split it. Move module, plugin, tools, executables and test related functions out of QtBuild.cmake into separate files. Do the same for many other things too. An additional requirement is that all the new Helpers files only define functions and macros. No global variable definitions are allowed, nor execution of commands with side effects. Some notes: qt_install_qml_files is removed because it's dead code. Some functions still need to be figured out, because they are interspersed and depend on various global state assignments.
