New features ------------ CMake's `AUTOMOC` and `AUTOUIC` now cache information extracted when parsing source files in `CMakeFiles/<ORIGIN>_autogen.dir/ParseCache.txt`. This leads to faster `<ORIGIN>_autogen` target rebuilds, because source files will be parsed again only if they're newer than the `ParseCache.txt` file. The parse cache will be recomputed if it is older than the CMake executable. `AUTOMOC` and `AUTOUIC` now check if `moc` or `uic` output files are older than the `moc` or `uic` executable. If an output file is older than the compiler, it will be regenerated. Therefore if a new `moc` or `uic` version is installed, all output files will be regenerated. `AUTOMOC` and `AUTOUIC` error and warning messages are more detailed. Internal changes ---------------- `moc` and `uic` output file names are not computed in the `_autogen` target anymore but in `cmQtAutoGenInitializer`. This makes the available at the configuration stage for improved dependency computations (to be done). In `AutogenInfo.cmake`, equally sized lists for "source file names", "source file flags" and "compiler output file names" are passed to the `_autogen` target. This replaces the separate file lists for `AUTOMOC` and `AUTOUIC`. Files times are read from the file system only once by using `cmFileTime` instances instead of `cmQtAutoGenerator::FileSystem::FileIsOlderThan` calls. All calls to not thread safe file system functions are moved to non concurrent fence jobs (see `cmWorkerPool::JobT::IsFence()`). This renders the `cmQtAutoGenerator::FileSystem` wrapper class obsolete and it is removed. Instead of composing a single large settings string that is fed to the `cmCryptoHash`, now all setting sub strings are fed one by one to the `cmCryptoHash` and the finalized result is stored. The `std::mutex` in `cmQtAutoGenerator::Logger` is tagged `mutable` and most `cmQtAutoGenerator::Logger` methods become `const`. Outlook ------- This patch provides the framework required to - extract dependencies from `.ui` files in `AUTOUIC`. These will help to address issue #15420 "AUTOUIC: Track uic external inputs". - generate adaptive `make` and `ninja` files in the `_autogen` target. These will help to address issue #16776 "AUTOUIC: Ninja needs two passes to correctly build Qt project". - generate (possibly empty) `moc` and `uic` files for all headers instead of a `mocs_compilation.cpp` file. This will help to address issue #17277 "AUTOMOC: Provide a option to allow AUTOMOC to compile individual " "moc_x.cxx instead of including all in mocs_compilation.cxx"
