I have a problem with a CMake path

[ljaviergranillo97]

When I compile my workspace I get the following error:

CMake Error at despot_tutorials/examples/laser_tag/CMakeLists.txt:18 (find_package):
  Could not find a package configuration file provided by "Despot" with any
  of the following names:

    DespotConfig.cmake
    despot-config.cmake

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