CMake Error at src/CMakeLists.txt:20 (find_package):
  By not providing "Findopentxs.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "opentxs", but
  CMake did not find one.

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

    opentxsConfig.cmake
    opentxs-config.cmake

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