Question

我必须下载zlib才能在我的项目中使用。我使用externlproject_add（）来下载所有zlib存储库，构建并安装它。之后，我想安装一个lib，它是zlib存储库的一部分：minizip。

如何设置对cmake的依赖？

zlib模块：

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 )
SET (MINIZIP_DIR ${CMAKE_CURRENT_BINARY_DIR}/ZLIB/src/ZLIB/contrib/minizip)

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}     
 )

 find_package(ZLIB REQUIRED)
 if(ZLIB_FOUND)
      add_subdirectory (${MINIZIP_DIR})
 endif(ZLIB_FOUND)

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）

使用这个zlib模块，我有一个错误，跟在目录

之后

/家庭/ LAIS / Imagens /剂/建造/ ZLIB / SRC / ZLIB /了contrib / minizip

我跑

时

还不存在

cmake ..

这是真的。还不存在。我应该告诉cmake它。但我不知道该怎么做。

如何在externalproject_add（）之后添加add_subdirectory？
