build: use modern cmake (#21589) Replace old-school cmake with the so-called "Modern CMake", meaning preferring using targets and properties over directory settings and variables. This allows greater flexibility, robustness and clarity over how the code works. The following deprecated commands will be replaced with their modern alternatives that operates on a specific target, rather than all targets in the current directory: - add_compile_options -> target_compile_options - include_directories -> target_include_directories - link_libraries -> target_link_libraries - add_definitions -> target_compile_definitions There are mainly four main targets that we currently use: nvim, libnvim, nvim-test (used by unittests) and ${texe} (used by check-single-includes). The goal is to explicitly define the dependencies of each target fully, rather than having everything be dependent on everything else.

# TODO(dundargoc): FindIconv is shipped by default on cmake version 3.11+. This
# file can be removed once we decide to upgrade minimum cmake version.
build: adjust how find order is prioritized Ensure bundled libraries and include directories are always searched first before any others. This will provide a more consistent experience as the search order of the builtin find_ functions can vary depending on system. This should make the build process faster when building with bundled deps as we limit the search to only the .deps directory. Separating the search between .deps and everything makes debugging find_-related problems simpler if you need to check how dependencies are found. For libraries, we divide the search process into the following order: 1. Only search in .deps directory and only search for static libraries. 2. Only search in .deps directory and search for all libraries. 3. Search everywhere and search for all libraries. Make an exception for FindLibintl.cmake as changing the search order seems to break some tests on macos.

build: remove libfindmacros library (#22423) Large parts the library weren't being used, and the parts that were was overly abstracted for our use case. Additionally, part of its use case was to abstract pkgconfig boilerplate, which is no longer needed as pkgconfig has been removed in favor of relying on cmake alone in 09118052cee5aef978d6075db5287c1b6c27381a.

mark_as_advanced(ICONV_INCLUDE_DIR ICONV_LIBRARY)
build: cmake cleanup (#22251) - Remove unused code - Use consistent casing. Variable names such as LibLuV_LIBRARIES is needlessly jarring, even if the name might be technically correct. - Use title casing for packages. find_package(unibilium) requires the find_module to be named "Findunibilium.cmake", which makes it harder to spot when scanning the files. Instead, use "Unibilium".
