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.

find_path2(LIBUV_INCLUDE_DIR uv.h)
find_library2(LIBUV_LIBRARY NAMES uv_a uv)
Revamp the build system. This achieves several goals: * Less reliance on scripts so we have better portability to Windows (though we still have a ways to go for proper Windows support). Luajit, luarocks, moonscript, and busted are all installed via CMake now. * Trying to make use of pkg-config to get the correct libraries. The latest libuv is still broken in this regard, but we'll at least be in a position to use it. * Allow the use of Ninja or make. The former runs faster in many environments, and automatically makes use of parallel builds. This also allows for system installed dependencies--though not through the Makefile just yet--and adds support for FreeBSD. This also make us build libuv and luajit as static libraries only, since we're only concerned about having static libraries for our bundled dependencies.

build: remove pkgconfig-related code (#22422) Cmake should already be able to find everything on its own.

set(LIBUV_LIBRARIES ${LIBUV_LIBRARY})
Deal with the missing dependencies for libuv. Since libuv.pc is broken at the moment, try to determine libuv's dependencies ourselves. This ports most of the checks from libuv into our CMake build, and fixes the build on other unix platforms.

cmake: Don't use check_library_exists for Win32 API libraries When building for X86 the CMake check_library_exists always fails to find functions from the Win32 API due to name mangling conventions. The convention for API functions is __stdcall and the CMake test code assumes __cdecl. Since these are libraries from the Windows API we can simply link against the libraries without checking for the functions.

fix(build): call find_package(Threads) before using its variables

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".
