CMake:包括柠檬库

Question

我只想将 Lemon 库添加到我的 CMakeLists.txt。当我不使用 CMake 时，我只是添加了“-lemon”并且一切正常，但现在我不知道将其添加到 CMake 文件的过程。

编辑确实包括我的CMakeLists.txt:

# Created by the script cgal_create_cmake_script_with_options
# This is the CMake script for compiling a set of CGAL applications.

project( ssp )


cmake_minimum_required(VERSION 2.6.2)
if("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" VERSION_GREATER 2.6)
  if("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}.${CMAKE_PATCH_VERSION}" VERSION_GREATER 2.8.3)
    cmake_policy(VERSION 2.8.4)
  else()
    cmake_policy(VERSION 2.6)
  endif()
endif()

set( CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true )

if ( COMMAND cmake_policy )

  cmake_policy( SET CMP0003 NEW )  

endif()

# CGAL and its components
find_package( CGAL QUIET COMPONENTS  )

if ( NOT CGAL_FOUND )

  message(STATUS "This project requires the CGAL library, and will not be compiled.")
  return()  

endif()

# include helper file
include( ${CGAL_USE_FILE} )


# Boost and its components
find_package( Boost REQUIRED )

if ( NOT Boost_FOUND )

  message(STATUS "This project requires the Boost library, and will not be compiled.")

  return()  

endif()

# include for local directory

# include for local package

set(CMAKE_CXX_FLAGS "-lemon")


# Creating entries for target: ssp
# ############################

add_executable( ssp  arrangement.cpp main.cpp polygonOperations.cpp scheduleGraph.cpp )

add_to_cached_list( CGAL_EXECUTABLE_TARGETS ssp )

# Link the executable to CGAL and third-party libraries
target_link_libraries(ssp   lemon ${CGAL_LIBRARIES} ${CGAL_3RD_PARTY_LIBRARIES} )

Answer 1

很简单，用target_link_libraries :

project(test)

add_executable(mine test.c)

target_link_libraries(mine m)

在这个例子中，我链接的是 libm。在您的情况下，m 将是 lemon。至少我认为，我不确定你的问题是库名称是 lemon 还是 emon 因为 -l 是标志和名称应遵循(即 -lm 链接 libm)。

对于我的简单示例，如果我运行 make VERBOSE=1(并删除不重要的行):

[100%] Building C object CMakeFiles/mine.dir/test.c.o
/usr/bin/cc    -o CMakeFiles/mine.dir/test.c.o   -c /home/tgallagher/temp/test.c
Linking C executable mine
/usr/local/bin/cmake -E cmake_link_script CMakeFiles/mine.dir/link.txt --verbose=1
/usr/bin/cc      CMakeFiles/mine.dir/test.c.o  -o mine -rdynamic -lm 

所以它首先编译源文件，然后将 -lm 放在链接器行上。
