2. 解压

进入到解压后的文件夹，执行下面命令：

cmake . && make && sudo make install

3. 编译nlopt文件

编译后会报错, Could not find “FindNLOPT.cmake”

By not providing "FindNLOPT.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "NLOPT", but
  CMake did not find one.
  
  Could not find a package configuration file provided by "NLOPT" with any of
  the following names:
    NLOPTConfig.cmake
    nlopt-config.cmake
    
  Add the installation prefix of "NLOPT" to CMAKE_PREFIX_PATH or set
  "NLOPT_DIR" to a directory containing one of the above files.  If "NLOPT"
  provides a separate development package or SDK, be sure it has been
  installed.

在CMakelist.txt中添加xxx.cmake所在的路径到查找路径。
解决以上报错的两种方法：

1. 添加 set (NLOPT_DIR "/home/qiancj/nlopt/")

2. 添加 set (CMAKE_PREFIX_PATH "pathtoxxx.cmake")

3. 添加 list(APPEND CMAKE_FIND_ROOT_PATH "pathtoxxx.cmake")

4. 参考

Cmake编译错误–怕忘，遇到些特殊的问题记下来-TODO
