c++ - 如何使用 zlib 安装 minizip？

Question

我有以下 cmake 文件要下载、构建和安装 zlib:

cmake_minimum_required ( VERSION 2.8.7 )
include (ExternalProject)

if(UNIX)
  # An external project for zlib 
  SET (GIT_URL https://github.com/madler/zlib.git) 
  SET (ZLIB_INSTALL ${CMAKE_CURRENT_BINARY_DIR}) 
  SET (ZLIB_INCLUDE ${CMAKE_BINARY_DIR}/include/zlib) 
  SET (ZLIB_STATIC  ${CMAKE_BINARY_DIR}/lib/libz.a )

  ExternalProject_Add(zlib     
    PREFIX zlib     
    GIT_REPOSITORY ${GIT_URL}     
    INSTALL_DIR ${ZLIB_INSTALL}     
    PATCH_COMMAND ${CMAKE_COMMAND} -E remove <SOURCE_DIR>/zconf.h     
    BUILD_IN_SOURCE 1     
    PATCH_COMMAND ""     
    CONFIGURE_COMMAND <SOURCE_DIR>/configure --prefix=<INSTALL_DIR> --includedir=${ZLIB_INCLUDE}     
  )

  SET (ZLIB_INCLUDE_DIR ${ZLIB_INSTALL}/include/zlib) 
  SET (ZLIB_LIBRARY "${ZLIB_INSTALL}")
  ADD_LIBRARY (ZLIB_LIB STATIC IMPORTED DEPENDS zlib)
  SET_TARGET_PROPERTIES (ZLIB_LIB PROPERTIES IMPORTED_LOCATION "${ZLIB_STATIC}")
endif(UNIX)

但是这个 cmake 文件只安装 zlib。我还想安装 minizip。 Minizip 是“zlib 的一部分”。在 zlib 存储库中有一个包含 minizip 的目录。

我怎样才能在同一个 cmake 文件中安装 minizip？是否可以？

minizip 在 zlib 存储库中:

- zlib
    - contrib
        - minizip
        - ....
    - ...
- ...

我有 cmake 文件来安装 minizip:

cmake_minimum_required(VERSION 2.8)

project(minizip)

set ( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11" )

set(BUILD_SHARED_LIBS OFF)

find_package (ZLIB REQUIRED)

if (ZLIB_FOUND) 
  set(ZLIB_LIBRARY ${CMAKE_BINARY_DIR}/ZLIB/src/ZLIB/contrib)
  SET (minizip ${CMAKE_BINARY_DIR}/lib/minizip)

  if(CMAKE_HOST_APPLE)
    set(PLATFORM __APPLE__)
  elseif(CMAKE_HOST_UNIX)
    set(PLATFORM unix)
  elseif(CMAKE_HOST_WIN32)
    set(PLATFORM _WIN32)
  else(CMAKE_HOST_APPLE)
    message(FATAL_ERROR "Not supported Platform")
    endif(CMAKE_HOST_APPLE)

  add_definitions(-D${PLATFORM})

set(SOURCE
  ${ZLIB_LIBRARY}/minizip/ioapi.c
  ${ZLIB_LIBRARY}/minizip/miniunz.c
  ${ZLIB_LIBRARY}/minizip/minizip.c
  ${ZLIB_LIBRARY}/minizip/unzip.c
  ${ZLIB_LIBRARY}/minizip/zip.c
)

if(WIN32)
    set(SOURCE ${SOURCE} ${ZLIB_LIBRARY}/minizip/iowin32.c)
endif(WIN32)

set(HEADERS
  ${ZLIB_LIBRARY}/minizip/crypt.h
  ${ZLIB_LIBRARY}/minizip/ioapi.h 
  ${ZLIB_LIBRARY}/minizip/miniunz.h
  ${ZLIB_LIBRARY}/minizip/unzip.h
)

if(WIN32)
    set(HEADERS ${HEADERS} ${ZLIB_LIBRARY}/minizip/iowin32.h)
endif(WIN32)

add_library(minizip ${SOURCE} ${HEADERS})
target_link_libraries(minizip PUBLIC "-static" ZLIB_STATIC)

add_dependencies ( minizip zlib)

install(
  TARGETS minizip EXPORT minizip-exports
  INCLUDES DESTINATION "include"
  RUNTIME DESTINATION "bin"
  LIBRARY DESTINATION "lib"
  ARCHIVE DESTINATION "lib"
)

install(
  FILES ${HEADERS}
  DESTINATION "${CMAKE_CURRENT_BINARY_DIR}/include/minizip"
)

ADD_LIBRARY (MINIZIP_LIB STATIC IMPORTED DEPENDS minizip)
SET_TARGET_PROPERTIES (MINIZIP_LIB PROPERTIES IMPORTED_LOCATION ${minizip})

万一()

我想在安装 minizip 之前，安装 zlib。
但是当我运行时

cmake ..

我有以下错误:

Make Error at modules/minizip.cmake:50 (add_library): Cannot find source file:

/home/lais/Imagens/agent/build/ZLIB/src/ZLIB/contrib/minizip/ioapi.c

CMake Error: Cannot determine link language for target "minizip". CMake Error: CMake can not determine linker language for target: minizip

我有一个顶级cmake，它需要这两个模块:

cmake_minimum_required( VERSION 2.8.7 )

# src : collect functions - depend on OS
if ( WIN32 )
    file ( GLOB SOURCES ${SOURCES} src/project/windows/*.cpp )
else ()     # if( UNIX )
    file ( GLOB SOURCES ${SOURCES} src/project/linux/*.cpp )
endif ()

# src : curl requests

option( BUILD_CURL_TESTS "Set to ON to build cURL tests." OFF )
# avoid running tests - set ON again in download version or if errors occur
option( RUN_CURL_TESTS "Set to ON to run cURL tests." OFF )

add_subdirectory ( lib/cpr )
include_directories ( ${CPR_INCLUDE_DIRS} )
include_directories ( ${CURL_INCLUDE_DIRS} )

# src : DtWinVer - Windows Version/Edition class
if ( WIN32 )
    add_subdirectory ( lib/dtwinver )
endif ()

# src = zlib

# src = minizip

set ( CMAKE_RUNTIME_OUTPUT_DIRECTORY "../bin" )
add_executable ( project-v${VERSION_MAJOR}.${VERSION_MINOR} ${SOURCES} )

add_dependencies ( project-v${VERSION_MAJOR}.${VERSION_MINOR} Boost)
add_dependencies ( project-v${VERSION_MAJOR}.${VERSION_MINOR} zlib)
add_dependencies ( project-v${VERSION_MAJOR}.${VERSION_MINOR} minizip)

endif ()

看起来你的源包不完整。minizip只是一个简单的文件minizip.c .为什么需要cmake ?只需编译它并链接到 zlib一切都会好起来的。
