1.2.3. qt_add_qml_module() を使用するように変更する (推奨)

qmake2cmake で作成された CMakeLists.txt は QMLファイルも含めて qt_add_resources() を使用しているために、 qt_add_qml_module() を使用するように変更する。

この変更は、QMLスクリプトコンパイラを通すために行う。

この変更を行うと、QMLのリソースパスに、URIのパス、およびQMLまでの相対パスが追加されるために、main.cpp の変更も必要となる。

1.2.4. 再利用可能なQMLモジュールの構築 (推奨)

再利用可能なQMLモジュールとするために、 サブディレクトリに CMakeLists.txt を作成し、元の CMakeLists.txt からサブディレクトリの CMakeLists.txt を使用するように変更する。

この変更を行うと、QMLのリソースパスが、URIのパスのみ変更されるために、main.cpp の変更も必要となる。
