* CMake: Make zstd config-based lookup quietAlexey Edelev2020-11-091-2/+4
| | | | | | | | | | | | | Make zstd config based lookup quiet and check for version variable as required for ZSTD target. Add IMPORTED_LOCATION by default for pkg-config based search. Expect that select_library_configurations will set correct value for ZSTD_LIBRARY.

* CMake: Locate zstd using CONFIGAlexey Edelev2020-11-081-21/+51

* CMake: pro2cmake: Specify library versions for 3rd party librariesAlexandru Croitor2020-08-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | If certain 3rd party libraries have a version that's not suitable for Qt, the configure summary should say so, rather than use them and fail at build time. With the current situation, we have to duplicate the version information from the configure.json files in helper.py, by assigning the version number as an extra find_package variable. Rerunning configurejson2cmake then embeds this version info into the qt_find_package calls in configure.cmake. Some of the Find modules are rewritten to take the specified version into account when looking for the libraries. This involves moving around the code for creating a target, after calling find_package_handle_standard_args() so we know if a good enough version was found.

* Fix static zstd linkageSimon Hausmann2019-05-241-1/+1
| | | | | | | | | Upstream's cmake build system installs libzstd_static for static builds, so look for that as well. Now we can also recommend installing it via vcpkg. Change-Id: I0ba4c45ecd90bf7b1c9f1e5f84a440caa976a23c Reviewed-by: Tobias Hunger <tobias.hunger@qt.io>
* Write find_dependency() calls in Qt Module config filesAlexandru Croitor2019-05-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces a new function called qt_find_package() which can take an extra option called PROVIDED_TARGETS, which associates targets with the package that defines those targets. This is done by setting the INTERFACE_QT_PACKAGE_NAME and INTERFACE_QT_PACKAGE_VERSION properties on the imported targets. This information allows us to generate appropriate find_dependency() calls in a module's Config file for third party libraries. For example when an application links against QtCore, it should also link against zlib and atomic libraries. In order to do that, the library locations first have to be found by CMake. This is achieved by embedding find_dependency(ZLIB) and find_dependency(Atomic) in Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake. The latter is picked up when an application project contains find_package(Qt5Core), and thus all linking dependencies are resolved. The information 'which package provides which targets' is contained in the python json2cmake conversion script. The generated output of the script contains qt_find_package() calls that represent that information. The Qt5CoreDependencies.cmake file and which which dependencies it contains is generated at the QtPostProcess stop. Note that for non-static Qt builds, we only need to propagate public 3rd party libraries. For static builds, we need all third party libraries. In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any scope, the targets on which the property is set, have to be GLOBAL. Also for applications and other modules to find all required third party libraries, we have to install all our custom Find modules, and make sure they define INTERFACE IMPORTED libraries, and not just IMPORTED libraries.
