CMake Warning at CMakeLists.txt:173 (find_package):
  By not providing "FindFLEX.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "FLEX", but
  CMake did not find one.

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

    FLEXConfig.cmake
    flex-config.cmake

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


CMake Warning at CMakeLists.txt:174 (find_package):
  By not providing "FindBISON.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "BISON", but
  CMake did not find one.

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

    BISONConfig.cmake

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


CMake Warning at CMakeLists.txt:178 (message):
  Missing Bison.

  You won't be able to generate source codes from changed flex/bison files.

  Compiling libyang should still works fine.
