编译

	$  mkdir build
	$  cd build/
	$  cmake ..
	$  make
	$  make install

测试

	$  ./hello_cmake
	install hello: cmake
	
	$ cat install_manifest.txt
	/usr/local/bin/cmake_examples_inst_bin
	/usr/local/lib/libcmake_examples_inst.so
	/usr/local/etc/cmake-examples.conf
	
	$  ls /usr/local/bin/
	cmake_examples_inst_bin
	$ ls /usr/local/lib
	libcmake_examples_inst.so
	$ ls /usr/local/etc/
	cmake-examples.conf
	$ ld_library_path=$ld_library_path:/usr/local/lib cmake_examples_inst_bin
	install hello: cmake

说明

这样install的目录为 /usr/local 如果想改变install的目录有三种方式。
方式1：
在cmakelists.txt 加入

set(cmake_install_prefix "${cmake_binary_dir}/install" cache string "the path to use for make install" force)

方式2：
在cmake构建工程的时候加入参数

cmake -dcmake_install_prefix=./install ..

./install可以是任何目录，别忘了最后的两个点。

方式3：
.make install 时指定安装路径

make destdir=./install
