pkg-config for premake

This module contains a pure lua implementation of the pkg-config utility that can be used in premake projects to query information about installed libraries.

To use it, simply install this module somewhere premake can find it. One way is to add it as a submodule of your premake project:

git submodule add https://github.com/tarruda/premake-pkgconfig pkgconfig

Then use pkgconfig.load to return a table with data about installed libraries:

local pkgconfig = require 'pkgconfig'
print(pkgconfig.load('zlib').cflags)
print(pkgconfig.load('glib-2.0').libs)

The load function will look for .pc files in a set of predefined search paths(see man pkg-config). Extra search paths can be provided either as the second argument or through the PKG_CONFIG_PATH environment variable:

pkgconfig.load('mylib', {'/opt/pkgconfig', '/home/user/pkgconfig'})
