求教，package.tools.xxx下面是如何自动取得所需的lib的？

[augustheart]

最近写规则有点摸不着头脑，package规则写下来发现include是对的，但是最后链接的时候居然一个静态库都没附加。而查看manifest则能看到有包含正确的link信息
这是我的规则。还没调整没优化，因为没搞清楚到底它是怎么工作起来的，一点点改着编译然后查看效果，最后发现越看越糊涂……
import("package.tools.autoconf").install(package, cfg)后面那些代码我是用来把wxwidgets安装后那古怪的文件分布规整用的。

package("wx")
	set_urls("https://github.com/wxWidgets/wxWidgets/releases/download/v$(version)/wxWidgets-$(version).7z")
	add_versions("3.2.1","3AA02ED68662A55FD8AB2B8AD3A534986554E8B1BAC0970C3E1D9AA9027F83F5")
	--set_sourcedir("$(projectdir)/third/wxwidgets_3_2_1")
	add_deps("z")
	add_deps("curl",{configs = {usesystem = true}})
	add_ldflags("-static","-mwindows")
	add_links("wx_mswu-3.2-i686-w64-mingw32",“wxtiff-3.2-i686-w64-mingw32" ,"wxjpeg-3.2-i686-w64-mingw32","wxpng-3.2-i686-w64-mingw32", "wxregexu-3.2-i686-w64-mingw32", "wxscintilla-3.2-i686-w64-mingw32")
	add_defines("__WXMSW__","_FILE_OFFSET_BITS=64")
add_syslinks("imm32","expat","rpcrt4","oleaut32","ole32","uuid","uxtheme","winspool","winmm","shell32","shlwapi","comctl32","comdlg32","advapi32","version","ws2_32","gdi32","oleacc","winhttp")
	on_install(function(package)
		local cfg = {"--disable-shared","--disable-tests"}
		--table.insert(cfg,"--enable-stl")
		table.insert(cfg,"--enable-monolithic")
		--table.insert(cfg,"--enable-permissive")
		import("package.tools.autoconf").install(package, cfg)
		local base = package:installdir()
		local tmpdir = "wx-3.2"
		local mvfunc = function(base,tmp)
			local inc = "include"
			os.cp(path.join(base,inc,tmp,"wx"),path.join(base,inc))
			os.rmdir(path.join(base,inc,tmp))
			local base1 = path.join(base .. "/lib","wx","include")
			for _,v in ipairs(os.dirs(base1 .. "/*")) do
				os.cp(path.join(v,"wx","setup.h"),path.join(base,inc,"wx"))
				os.cp(path.join(v,"wx/*"),path.join(base,inc,"wx"))
				os.rmdir(path.join(base,"lib","wx"))
				break
			end
		end
		--mvfunc(base,tmpdir)
	end)
package_end()

target是这么写的

add_requires("wx","sol2","lua","rapidjson")
target("wxLeiTools")
    set_kind("binary")
	add_packages("wx","lua","rapidjson","sol2")
    add_ldflags("-static","-s")
    add_files("*.cpp","*.c","*.rc")
target_end()

下面是编译效果：
可以看到，头文件正确引入了

看自动找到的库名 不是很明显么，你 add_links 里面没写对，明明安装后 lib 目录下是 wx_mswu-3.2-x86_64-w64-mingw32

你去配置 wx_mswu-3.2-i686-w64-mingw32 ，注意 x86_64 不是 i686

add_links("wx_mswu-3.2-i686-w64-mingw32",“wxtiff-3.2-i686-w64-mingw32" ,"wxjpeg-3.2-i686-w64-mingw32","wxpng-3.2-i686-w64-mingw32", "wxregexu-3.2-i686-w64-mingw32", "wxscintilla-3.2-i686-w64-mingw32")

[augustheart]

我的天哪，这个低级错误……………………我是i686跑通的换成x64怎么都不行。我反反复复看了好几遍，这行也看了八百遍，愣是没转过这道弯来。
求证一下，在package里面写add_links是不是会完全覆盖package.tools.xxx自动探测的结果？

嗯，默认自动扫，但顺序未定义，对一些单库小包 比较方便配置，大包建议自己 add_links 控制链接顺序。
