Subject: [PATCH] Make building minizip optional, if your linux distro supplies
 a minizip binary (e.g. in the zlib-bin package on debian) you might as well
 use it instead of building this one. Note that this isn't implemented in the
 minizip CMakeLists.txt, but at the higher level (kicad) that includes the
 minizip subdirectory, so that the whole minizip directory can be dropped from
 the shipped source tree if it isn't needed on your distro. This makes the
 source package a fraction smaller and removes possible complications of
 having a different license on the minizip code to the rest of kicad.
