CMake Error at CMakeLists.txt:12 (find_package):
  By not providing "FindQt5Transitional.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "Qt5Transitional", but CMake did not find one.

  Could not find a package configuration file provided by "Qt5Transitional"
  with any of the following names:

    Qt5TransitionalConfig.cmake
    qt5transitional-config.cmake

  Add the installation prefix of "Qt5Transitional" to CMAKE_PREFIX_PATH or
  set "Qt5Transitional_DIR" to a directory containing one of the above files.
  If "Qt5Transitional" provides a separate development package or SDK, be
  sure it has been installed.
