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})
