cmakelists添加第三方庫

1.設置第三方庫路徑

SET(INC_DIR "usr/local/include/")
SET(LINK_DIR "usr/local/lib")

2.設置頭文件搜索路徑

include_directories(${INC_DIR})

3.指定要鏈接的路徑

link_directories(${LINK_DIR})

通過log4cplus（C++日志庫）舉例子

之后生成可執行文件

include_directories(${INC_DIR}/log4cplus)
file(GLOB SRCLOG src/Log4jcpp.cpp)
add_executable(demolog ${SRCLOG} )
target_link_libraries(demolog log4cplus)
