bundled LCC fails to build with GCC-15

1

`constexpr` is a reserved keyword in C23. GCC-15 switches go C23 by default. LCC uses function named `constexpr` a lot, and then fails to build. https://bugs.gentoo.org/944329

CMake 4 raised minimum compatible version to CMake 3.5. See https://gitlab.kitware.com/cmake/cmake/-/issues/26698 and https://gitlab.kitware.com/cmake/cmake/-/issues/26613 Also see https://bugs.gentoo.org/951814 for bug occurring in Gentoo testing

uint is apparently defined in default includes in gcc, but is missing in clang; https://github.com/PixlOne/logiops/blob/628ab937a25724c1f21e7edf25c8e5aaff82c691/src/logid/config/schema.h#L69 see bug https://bugs.gentoo.org/919053

CMake 4 bumped minimum supported version of CMake to 3.5. Zydis 3.1.2 has minimum required as 3.1, and it fails to compile. Gentoo bug https://bugs.gentoo.org/951986 See CMake changelog https://gitlab.kitware.com/cmake/cmake/-/issues/26698 and...
