   4 Subject: [PATCH] Add a CMakeFile.txt to ease cross-compilation
   5
   6 Info-ZIP's UnZip 6.0 has a complex, hand-crafted Makefile with a
   7 companion configure script which try to support an extremely wide
   8 range of UNIX-like operating systems. The result is an overly complex
   9 mass of code that does not support cross-compilation in several ways.
  10
  11 Zip 3.0 has a similar build system, and has as many as 6 patches in
  12 Buildroot to cross-compile [0]. UnZip fails at building even with
  13 these patches adapted and a few more on top of them.
  14
  15 Instead of tweaking and fixing a huge and complex build system, skip
  16 it entirely and add a pretty simple CMakeLists.txt that cross-compiles
  17 smoothly using CMake. It also preserves all of the Buildroot-provided
  18 build options and flags as the original Makefile does.
