From e9a797799ee7e81d1cd113ba56f62705ae150e5c Mon Sep 17 00:00:00 2001 From: Alexandru Croitor Date: Mon, 2 Dec 2019 18:03:47 +0100 Subject: CMake: Add Qt6 forward compatible CMake API and targets Create Qt:: versionless targets for libraries and tools. So Qt::Core will link to Qt5::Core. Add additional feature properties to targets, with the same name they have in Qt6: QT_ENABLED_PUBLIC_FEATURES, QT_DISABLED_PUBLIC_FEATURES, QT_ENABLED_PRIVATE_FEATURES, QT_DISABLED_PRIVATE_FEATURES, to be forward-compatible with Qt6. Prefix properties with INTERFACE_ for interface libraries. Create functions with no major version in their prefix, so qt_foo instead of qt5_foo. The non-versioned functions will call the versioned functions, depending on the value of QT_DEFAULT_MAJOR_VERSION, which can be set by an application developer before finding the Qt package. Set QT_DEFAULT_MAJOR_VERSION to 5 if the value has not been defined in the current scope. Application developers can set QT_NO_CREATE_VERSIONLESS_FUNCTIONS to TRUE before calling find_package(Qt5) to suppress creation of the non-versioned functions. Application developers can set QT_NO_CREATE_VERSIONLESS_TARGETS to TRUE before calling find_package(Qt5) to suppress creation of the non-versioned targets. Setting these can be useful when both find_package(Qt5) and find_package(Qt6) are in the same project. If none of these are set by the user, then the first find_package(Qt5) will create versionless targets with the major version being "5", which means the second find_package(Qt6) will not create versionless targets. Handle versionless plugin names in qt_import_plugins, so both Qt::QCocoaIntegrationPlugin and Qt5/6::QCocoaIntegrationPlugin are recognized by the function. Allow specifying multiple types in EXCLUDE_BY_TYPE in qt_import_plugins, to be consitent with the Qt 6 version. Make sure to set the QT_PLUGIN_CLASS_NAME property to compatible with Qt 6.
