CMake和Linux编程：find_package的使用

1.第一个CMake例子

　　在 t1 目录建立 main.c 和 CMakeLists.txt(注意文件名大小写)：
　　main.c 文件内容：

//main.c

#include <stdio.h>

int main()

{

    printf(“Hello World from t1 Main!n”);

    return 0;

}

　CmakeLists.txt 文件内容：

PROJECT (HELLO)

SET(SRC_LIST main.c)

MESSAGE(STATUS "This is BINARY dir " ${HELLO_BINARY_DIR})

MESSAGE(STATUS "This is SOURCE dir "${HELLO_SOURCE_DIR})

ADD_EXECUTABLE(hello ${SRC_LIST})

 PROJECT (HELLO)

 SET(SRC_LIST main.c)

 MESSAGE(STATUS "This is BINARY dir " ${HELLO_BINARY_DIR})

 MESSAGE(STATUS "This is SOURCE dir "${HELLO_SOURCE_DIR})

 ADD_EXECUTABLE(hello SRC_LIST)

2.第二个CMake例子

CmakeLists.txt 文件内容：

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(normal_distributions_transform)

FIND_PACKAGE(PCL 1.8 REQUIRED)

include_directories(${PCL_INCLUDE_DIRS})

link_directories(${PCL_LIBRARY_DIRS})

add_definitions(${PCL_DEFINITIONS})

add_executable(normal_distributions_transform normal_distributions_transform.cpp )

target_link_libraries (normal_distributions_transform ${PCL_LIBRARIES})
