Compiling a static executable with CMake
Solution 1
As global CMake settings, add these lines before add_executable, valid for gcc/clang:
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
set(BUILD_SHARED_LIBS OFF)
set(CMAKE_EXE_LINKER_FLAGS "-static")
On Modern CMake (3.x+ - target_link_libraries doc), you can apply the flag to specific targets, in this way:
target_link_libraries(your_target_name -static)
If you're using MSVC, you have to set the compiler and linker flags:
set(CMAKE_FIND_LIBRARY_SUFFIXES ".lib")
target_compile_options(your_target_name [PUBLIC|PRIVATE] /MT)
target_link_options(your_target_name [PUBLIC|PRIVATE] /INCREMENTAL:NO /NODEFAULTLIB:MSVCRT)
and if you are using MFC, you need to specify the flag to 1
see here:
set(CMAKE_MFC_FLAG 1)
Solution 2
Add these lines after add_executable(MyExec "main.c")
(for exemple) :
target_link_libraries(MyExec PUBLIC "-static")
or before : link_libraries("-static")

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})
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?
