title: Compiling a static executable with CMake
body: <p>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).</p>
  
  <pre><code>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})
  </code></pre>
  
  <p>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?</p>
