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.

build: CMake: do not set CMP0059 to old (#10363) Keeps using add_definitions for compatibility with older CMake. Newer CMake (3.12) would have `add_compile_definitions`, but it is not required, since `add_defitions` was meant to be used for compile/preprocessor definitions initially anyway.
