CMake Error at CMakeLists.txt:12 (find_package):
  By not providing "FindKF5Wallet.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "KF5Wallet", but CMake did not find one.

  Could not find a package configuration file provided by "KF5Wallet"
  (requested version 5.18.0) with any of the following names:

    KF5WalletConfig.cmake
    kf5wallet-config.cmake

  Add the installation prefix of "KF5Wallet" to CMAKE_PREFIX_PATH or set
  "KF5Wallet_DIR" to a directory containing one of the above files.  If
  "KF5Wallet" provides a separate development package or SDK, be sure it has
  been installed.
