I am trying to cross compile libzip-1.5.1 having previously successfully complied zlib-1.2.11 (these are required by libzip and I have installed in a local home path), but I am experiencing problems with the cmake's process.

The script I use to build and compile (from a build directory into the libzip's sources folder) is the following:

#!/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

But at 94 % of building process, I get the following errors:

It seems that cmake cannot find the compiled zlib libraries, even if the paths seems to be well configured (or not ?).

Do some has experienced similar issues with libzip ?
Is there any addition cmake's macro that would solve this issue ?

---- UPDATE ----

I actually get rid of this error suppressing building task for zipcmp, zipmerge and ziptool (since I don't need them) commenting the lines:

#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})

into src/CMakeLists.txt.
Then I compiled the libs using make -j 8 zip and then make install/fast.
It still returns the error

but I don't care about it since I have the libs and headers installed in the install dir, and this is what I need.

this one is important

SET(CMAKE_SYSTEM_NAME Linux)

this one not so much

SET(CMAKE_SYSTEM_VERSION 1)

specify the cross compiler

SET(CMAKE_C_COMPILER /your/toolchain/path/bin/yourcompile-gcc)
SET(CMAKE_CXX_COMPILER /your/toolchain/path/bin/yourcompile-g++)

where is the target environment

SET(CMAKE_FIND_ROOT_PATH /your/rootfs/path)

search for programs in the build host directories

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)

for libraries and headers in the target directories

SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
