-- If you want to known more usage about xmake, please see https://xmake.io
--
-- ## FAQ
--
-- You can enter the project directory firstly before building project.
--
-- $ cd projectdir
--
-- 1. How to build project?
--
-- $ xmake
--
-- 2. How to configure project?
--
-- $ xmake f -p [macosx|linux|iphoneos ..] -a [x86_64|i386|arm64 ..] -m [debug|release]
--
-- 3. Where is the build output directory?
--
-- The default output directory is `./build` and you can configure the output directory.
--
-- $ xmake f -o outputdir
-- $ xmake
--
-- 4. How to run and debug target after building project?
--
-- $ xmake run [targetname]
-- $ xmake run -d [targetname]
--
-- 5. How to install target to the system directory or other output directory?
--
-- $ xmake install
-- $ xmake install -o installdir
--
-- 6. Add some frequently-used compilation flags in xmake.lua
--
-- @code
-- -- add debug and release modes
-- add_rules("mode.debug", "mode.release")
--
-- -- add macro definition
-- add_defines("NDEBUG", "_GNU_SOURCE=1")
--
-- -- set warning all as error
-- set_warnings("all", "error")

-- -- set language: c99, c++11
-- set_languages("c99", "c++11")
--
-- -- set optimization: none, faster, fastest, smallest
-- set_optimize("fastest")
--
-- -- add include search directories
-- add_includedirs("/usr/include", "/usr/local/include")
--
-- -- add link libraries and search directories
-- add_links("tbox")
-- add_linkdirs("/usr/local/lib", "/usr/lib")
