 {{{
 CMake Error at CMakeLists.txt:30 (find_package):
   By not providing "FindLIBCXX.cmake" in CMAKE_MODULE_PATH this project
 has
   asked CMake to find a package configuration file provided by "LIBCXX",
 but
   CMake did not find one.

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

     LIBCXXConfig.cmake
     libcxx-config.cmake

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