libzip Linux交叉编译配置

Question

我正在尝试交叉编译 libzip -1.5.1，之前我已经成功地编写了zlib-1.2.11 (这些是libzip所必需的，并且我已经安装在本地主路径中)，但是我在cmake的过程中遇到了问题。

用于构建和编译(从build目录到libzip的sources文件夹)的脚本如下：

#!/bin/sh

PREFIX=${PWD}/install
CCPATH=/opt/arm64/gcc-linaro-6.3.1-2017.02-rc2-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf
ZLIBPATH=${PWD}/../../zlib-1.2.11/

# here is where zlib is installed
# ZLIBINSTALLEDPATH contains include, lib, share directories
ZLIBINSTALLEDPATH=${ZLIBPATH}/build_armhf64/install/

export PKG_CONFIG_PATH="${PKG_CONFIG_PATH}:${ZLIBINSTALLEDPATH}/lib/pkgconfig/"
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${ZLIBINSTALLEDPATH}/lib/"
export CMAKE_AR=${CCPATH}-ar
export CC=${CCPATH}-gcc
export CXX=${CCPATH}-g++
export CMAKE_LINKER=${CCPATH}-ld
export CMAKE_RANLIB=${CCPATH}-ranlib
export CMAKE_OBJDUMP=${CCPATH}-objdump
export CMAKE_OBJCOPY=${CCPATH}-objcopy
export CMAKE_STRIP=${CCPATH}-strip
#export CMAKE_READELF=${CCPREFIX}-readelf
export CMAKE_NM=${CCPATH}-nm

cmake -DCMAKE_INSTALL_PREFIX=${PREFIX} \
    -DZLIB_INCLUDE_DIR=${ZLIBINSTALLEDPATH}/include/  \
    -DZLIB_LIBRARY=${ZLIBINSTALLEDPATH}/lib/  \
     ../
make -j 8

但是，在94 %的建设过程中，我得到以下错误：

看来cmake找不到编译好的zlib库，即使路径配置得很好(或者不是?)。

有些人在libzip上也遇到过类似的问题吗？是否有任何额外的cmake宏可以解决这个问题？

--更新-

实际上，我消除了为zipcmp、zipmerge和 rid工具(因为我不需要它们)的构建任务，并对行进行了注释：

#ADD_EXECUTABLE(zipcmp zipcmp.c ${SRC_EXTRA_FILES})
#TARGET_LINK_LIBRARIES(zipcmp zip)
#INSTALL(TARGETS zipcmp RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR})

#ADD_EXECUTABLE(zipmerge zipmerge.c ${SRC_EXTRA_FILES})
#TARGET_LINK_LIBRARIES(zipmerge zip)
#INSTALL(TARGETS zipmerge RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR})

#ADD_EXECUTABLE(ziptool ziptool.c ${SRC_EXTRA_FILES})
#TARGET_LINK_LIBRARIES(ziptool zip)
#INSTALL(TARGETS ziptool RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR})

转化为src/CMakeLists.txt。然后，我使用make -j 8 zip和make install/fast编译了库。它仍然返回错误。

但是我不关心它，因为我在安装dir中安装了lib和头，这就是我所需要的。
