# Build our bundled minizip.
|
||
|
|
#
|
||
|
|
# It is built as a static relocatable library, and linked into any target that
|
||
|
|
# requires it. Other targets in OpenJK that consume need to add
|
||
|
|
# MINZIP_INCLUDE_DIRS and MINIZIP_LIBRARIES to their lists of include
|
||
|
|
# directories and target link libraries.
|
||
|
|
#
|
||
|
|
# The bundled copy is produced by taking the files ioapi.{c,h} and unzip.{c,h}
|
||
|
|
# from the contrib/minizip directory of the zlib release tarball. The only
|
||
|
|
# changes applied are modifications of the macros ALLOC and TRYFREE in unzip.c,
|
||
|
|
# and a compatibility definition of the macro OF in include/ioapi.h
|
||
|
|
#
|
||
|
|
# Since minizip is expected to be reference by user code as
|
||
|
|
#
|
||
|
|
# #include <minizip/unzip.h>
|
||
|
|
#
|
||
|
|
# the public header files are split into the include/minizip subdirectory.
|
||
|
|
#
|
||
|
|
# The current bundled copy comes from the zlib 1.2.8 release.
|
||
|
|
|
||
|
|
# These settings only apply to this directory.
