* Reformat CMake code
* Bump minimum CMake version to 3.12
* Add target sources separately via `target_source()`
* Make `tr_win32_app_info()` add target sources on its own
* Don't use `include_directories()`
* Don't use `add_definitions()`
* Limit use of `add_compile_options()`
* Move VDKQueue target declaration to a subdirectory
* Add `tr_disable_source_files_compile()` helper
* Add `tr_target_glib_resources()` helper
* Add `tr_gettext_msgfmt()` helper
* Enable AUTOUIC for Qt client
* Enable AUTORCC for Qt client
* Remove AUTO{MOC,RCC,UIC} source group overrides
* Add `tr_target_idl_files()` helper
* Move source group setup to `tr_qt_add_translation()`
* Add `tr_target_xib_files()` helper
* Prefer `target_sources()` to intermediate variables
* Use explicit visibility versions of `target_*()` commands
* Prefer genexes to conditions in `target_*()` commands
* Add `tr_allow_compile_if()` helper
* Leave only top-level `project()`, remove the rest
* Minor fixups
* Fixup Mac QL plugin install
* Fixup IDE target folders and source groups
* Compile images into an assets catalog
* Optionally sign resulting Mac bundle
* Move 3rd-party/utility/test targets to their own folders
* Enable ARC via compile options unconditionally
* Install base and localized resources into correct directory
This seems like a Xcode quirk: if subdirectory containing the resource file
matches the destination directory name (and probably if there's more than one
resource file being installed there), the resulting folder structure then
contains an extra subdirectory, i.e. Resources/dirname/dirname/resname.
* Group source files for better structure in IDEs (Xcode, VS)
* Remove Xcode project
Using Xcode is still possible via "Xcode" CMake generator.
* Use ad-hoc signature if one is not specified
* Always use ad-hoc signature on link, leave proper signing to CPack
* Install localized resources into correct directory (QL plugin)
* Don't include CTest (we don't use additional targets it provides)
* Revert "Remove Xcode project"
This reverts commit dc069f654f.
