QtはGUI関連のライブラリのようなので取りあえず飛ばして問題なさそう。やっとプログラムに入りそう。
なお出ていたエラーは以下のような感じ
Could not find a package configuration file provided by “Qt5” with any of
the following names:
Qt5Config.cmake
qt5-config.cmake
Add the installation prefix of “Qt5” to CMAKE_PREFIX_PATH or set “Qt5_DIR”
to a directory containing one of the above files. If “Qt5” provides a
separate development package or SDK, be sure it has been installed.
