I have the following cmake file to download, build and install 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 "${ZLIB_STATIC}")
endif(UNIX)
But this cmake file only install zlib. I want also install minizip. Minizip is "part of zlib". In the zlib repository has a directory that has minizip.
How can I also install minizip in the same cmake file? Is it possible?
The minizip is inside zlib repository:
- zlib
- contrib
- minizip
- ....
- ...
- ...
I have cmake file to install minizip:
cmake_minimum_required(VERSION 2.8)
project(minizip)
set ( CMAKE_CXX_FLAGS "${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})
endif()
I want before install minizip, install zlib. But when I run
cmake ..
I have the following error:
Make Error at modules/minizip.cmake:50 (add_library): Cannot find source file:
