[Tarantool-patches] [v2][PATCH 4/5] build/ninja: create file lists outside of cmake commands

[Sergey Bronnikov via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

Patch adds a last change required for building LuaJIT with Ninja - using
glob inside CMake commands (add_custom_command and
set_source_files_properties) breaks buildng with Ninja.

By default CMake generates files suitable for building a project with
Make. However, it allows to generate files for Ninja too. Ninja [1] may
build project a bit faster than Make, see comparison in [2].

How-to build with Ninja:

$ cmake -G Ninja -B build -S .
$ cmake --build build --parallel
