After 2.5.7 to support the construction of Vala programs, we need to apply the add_rules("vala") rule, and the glib package is necessary.
related issues: #1618
add_values("vala.packages") is used to tell valac which packages the project needs, it will introduce the vala api of the relevant package, but the dependency integration of the package still needs to be downloaded and integrated through add_requires("lua").
Console program
lua
add_rules("mode.release", "mode.debug")
add_requires("lua", "glib")
target("test")
set_kind("binary")
add_rules("vala")
add_files("src/*.vala")
add_packages("lua", "glib")
add_values("vala.packages", "lua")Static library program
After v2.5.8, we continue to support the construction of library programs. The exported interface header file name can be set through add_values("vala.header", "mymath.h"), and through add_values("vala.vapi", "mymath -1.0.vapi") Set the name of the exported vapi file.
