CMake error about boost

[ze-n-g]

After installed, an error occurs:

CMake Error at /usr/local/lib/cmake/iipl/iiplTargets.cmake:61 (set_target_properties):
  The link interface of target "iipl" contains:

    Boost::filesystem

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

Call Stack (most recent call first):
  /usr/local/lib/cmake/iipl/iiplConfig.cmake:27 (include)
  CMakeLists.txt:26 (find_package)

A naive solution: add boost in CMakeList.txt before find_package(iipl REQUIRED)

find_package(Boost COMPONENTS filesystem)
