Question

我尝试将cmake与外部库一起使用，但我不能。我使用minGW和g ++编译器。我的项目组织如下：项目/

的CMakeLists.txt
SRC
- 的main.cpp
LIB
- 赢
  - 86
    - SDL2-2.0.3（包含SDL2.dll，SDL2.lib，SDL2main.lib和SDL2test.lib
包括
- SDL2（包含所有标题）
仓

cmake生成器工作`cmake -G＆＃34; Eclipse CDT4 - Unix Makefiles＆＃34;

我的cmake文件： `

    #
    # File generated by CMakeBuilder
#
#
cmake_minimum_required(VERSION 2.6)
PROJECT ( project CXX )


################ INCLUDE Libs ####################

SET (CMAKE_INCLUDE_PATH "${PROJECT_SOURCE_DIR}/include/")
SET (CMAKE_LINKER_PATH "${PROJECT_SOURCE_DIR}/lib/win/x86/SDL2-2.0.3/")

message(STATUS "INCLUDE_PATH: ${CMAKE_INCLUDE_PATH}" )
message(STATUS "LINKER_PATH: ${CMAKE_LINKER_PATH}" )

INCLUDE_DIRECTORIES(${CMAKE_INCLUDE_PATH})
LINK_DIRECTORIES(${CMAKE_LINKER_PATH})

set (CMAKE_CXX_FLAGS "-lSDL2main -lSDL2 -lmingw32 ")

#Generate file source

file( GLOB_RECURSE  source_files  src/*)

ADD_EXECUTABLE(project ${source_files})
set(EXECUTABLE_OUTPUT_PATH bin/${CMAKE_BUILD_TYPE})

但是当我启动make时，我得到了这个错误：

`

        Makefile:75: recipe for target 'all' failed

` 实际上我不想把我的lib放在minGW文件夹中以保持其他人的构建。

谢谢你的帮助
