CMake Error at CMakeLists.txt:9 (find_package):
  By not providing "FindEbml.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Ebml", but
  CMake did not find one.

  Could not find a package configuration file provided by "Ebml" (requested
  version 1.3.5) with any of the following names:

    EbmlConfig.cmake
    ebml-config.cmake

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