+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.
