By not providing "FindGeographicLib.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "GeographicLib", but CMake did not find one.

  Could not find a package configuration file provided by "GeographicLib"
  with any of the following names:

    GeographicLibConfig.cmake
    geographiclib-config.cmake

  Add the installation prefix of "GeographicLib" to CMAKE_PREFIX_PATH or set
  "GeographicLib_DIR" to a directory containing one of the above files.  If
  "GeographicLib" provides a separate development package or SDK, be sure it
  has been installed.

编译robot_localization这个包的时候，报错如上。
cmake文件如下：

# Geographiclib installs FindGeographicLib.cmake to this non-standard location
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "/usr/share/cmake/geographiclib/")
find_package(GeographicLib REQUIRED)

尝试了多种方法( 从官网https://sourceforge.net/projects/geographiclib/下载安装包，GeographicLib-1.52.tar.gz，依然报错，这种方法无效)，下面的方法验证有效：

sudo apt-get install ros-kinetic-geographic-*
sudo apt-get install geographiclib-*
sudo apt-get install libgeographic-*

然后编译成功。
