From 992a497e9c5c421d3931e02a01e9d7c159f27135 Mon Sep 17 00:00:00 2001 From: Luca Ceresoli Date: Thu, 26 Nov 2015 12:49:10 +0100 Subject: [PATCH] Add a CMakeFile.txt to ease cross-compilation Info-ZIP's UnZip 6.0 has a complex, hand-crafted Makefile with a companion configure script which try to support an extremely wide range of UNIX-like operating systems. The result is an overly complex mass of code that does not support cross-compilation in several ways. Zip 3.0 has a similar build system, and has as many as 6 patches in Buildroot to cross-compile [0]. UnZip fails at building even with these patches adapted and a few more on top of them. Instead of tweaking and fixing a huge and complex build system, skip it entirely and add a pretty simple CMakeLists.txt that cross-compiles smoothly using CMake. It also preserves all of the Buildroot-provided build options and flags as the original Makefile does.
