用CMake编译静态可执行文件 [英] Compiling a static executable with CMake

问题描述

对于一个项目，我需要创建一个包含所有我使用的库（opencv，cgal）的可执行文件，以便在没有那些库的计算机上执行它。目前，这是我的CMakeLists.txt（我使用linux）。

for a project I need to create an executable that includes all the libraries that I used (opencv, cgal) in order to execute it on a computer that has not those libraries. Currently, this is my CMakeLists.txt (I use linux).

cmake_minimum_required(VERSION 2.8)
#set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -Wall")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -Wall -O2")
project( labeling )
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
add_library(OpenCV STATIC IMPORTED)
add_library(CGAL STATIC IMPORTED COMPONENTS Core)
add_library(GMP STATIC IMPORTED)
find_package(OpenCV REQUIRED)
find_package(CGAL QUIET COMPONENTS Core )
find_library(GMP_LIBRARY gmp /usr/lib)

include(src)
include( ${CGAL_USE_FILE} )
include( CGAL_CreateSingleSourceCGALProgram )


set(EXECUTABLE_OUTPUT_PATH ../bin)
set(CMAKE_EXE_LINKER_FLAGS "-static-libgcc -static-libstdc++")

include_directories( src )
include_directories( ${OpenCV_INCLUDE_DIRS} )

file(GLOB_RECURSE nei_SRC "src/*.cpp")
add_executable( nei_segmentation ${nei_SRC})
target_link_libraries( nei_segmentation ${OpenCV_LIBS} ${GMP_LIBRARY})

在这种方式下，我的可执行文件中只包含GMP和其他一些c ++库。我的问题是：如何创建一个makefile，以便以静态方式自动包括所有的库，并只创建一个包含所有库的大可执行文件？你可以帮我吗？

In such a way only GMP and some other c++ libraries are included in my executable. My question is: How can I create a makefile in order to automatically including all the libraries in a static manner and creating only a "big" executable that contains all the libraries? Can you help me?

推荐答案

在add_executable之前添加这些行

add these lines before add_executable

SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static")
