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.

	bool "unzip"

	help

	  UnZip is an extraction utility for archives compressed in

	  .zip format (also called "zipfiles"). Although highly

	  compatible both with PKWARE's PKZIP and PKUNZIP utilities

	  for MS-DOS and with Info-ZIP's own Zip program, our primary

	  objectives have been portability and non-MSDOS

	  functionality.
