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
