meson: Various improvements Bumps minimum version to 0.51.0 - Remove all intermediate static libraries. They serve no purpose and are just add a bunch of boilerplate for managing dependencies and options. It's now managed as a list of files which are compiled into libwlroots directly. - Use install_subdir instead of installing headers individually. I've changed my mind since I did that. Listing them out is annoying as hell, and it's easy to forget to do it. - Add not_found_message for all of our optional dependencies that have a meson option. It gives some hints about what option to pass and what the optional dependency is for. - Move all backend subdirectories into their own meson.build. This keeps some of the backend-specific build logic (especially rdp and session) more neatly separated off. - Don't overlink example clients with code they're not using. This was done by merging the protocol dictionaries and setting some variables containing the code and client header file. Example clients now explicitly mention what extension protocols they want to link to. - Split compositor example logic from client example logic. - Minor formatting changes 5 years ago			`wlr_files += files(`

build: check if libinput supports hold gestures Add a project argument (LIBINPUT_HAS_HOLD_GESTURES) to allow building against old versions of libinput. 3 years ago
build: check if libinput supports high-res scroll Starting with Linux Kernel v5.0 two new axes are available for mice that support high-resolution wheel scrolling: REL_WHEEL_HI_RES and REL_HWHEEL_HI_RES. Both axes send data in fractions of 120 where each multiple of 120 amounts to one logical scroll event. Fractions of 120 indicate a wheel movement less than one detent. Three new events are now available on libinput: LIBINPUT_EVENT_POINTER_SCROLL_WHEEL, LIBINPUT_EVENT_POINTER_SCROLL_FINGER, and LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS. These events replace the LIBINPUT_EVENT_POINTER_AXIS event, so new clients should simply ignore that event. Also, two new APIs are available to access the high-resolution data: libinput_event_pointer_get_scroll_value() and libinput_event_pointer_get_scroll_value_v120(). Add a project argument (LIBINPUT_HAS_SCROLL_VALUE120) to allow building against old versions of libinput or, where high-resolution scroll is available, support it. 3 years ago			`# libinput hold gestures and high resolution scroll are available since 1.19.0`
