Use libxmake to build binary with xmake lua apis

[waruqi]

xmake provides a lot of practical module interfaces, we can use them to build a binary executable program independent of xmake, which is completely independent of xmake.

It can be executed independently without using xmake to load it.

Example

https://github.com/xmake-io/xmake/tree/dev/tests/projects/xmake_cli/hello

Create project

$ xmake create -t xmake.cli -l c test
$ create test ...
  [+]: xmake.lua
  [+]: src/lni/main.c
  [+]: src/lua/main.lua
  [+]: .gitignore
create ok!

Build project

please run xrepo update-repo to update repositories first. It will install latest libxmake package.

$ cd test
$ xmake
[ 40%]: archiving.luafiles test
[ 60%]: cache compiling.release src/lni/main.c
[ 80%]: linking.release test
[100%]: build ok, spent 1.548s
$ xmake run
hello xmake!
$ ./build/macosx/x86_64/release/test
