如何让cmake找到PyQt5来构建krita？

Question

我正在从源代码构建krita，每当运行cmake .. -DCMAKE_PREFIX_PATH=/Path/to/PyQt5或cmake .. -DPYQT_SIP_DIR_OVERRIDE=Path/to/PyQt5时，都会收到此警告，但它找不到PyQt5：

The following OPTIONAL packages have not been found:

 * PyQt5 (required version >= 5.6.0), Python bindings for Qt5., <https://www.riverbankcomputing.com/software/pyqt/download5>

当我运行locate或find时，它显示我在如下位置有PyQt5：

• ~/anaconda3/share/sip/PyQt5
• /usr/share/sip/PyQt5
• ~/anaconda3/share/sip/PyQt5
• ~/anaconda3/pkgs/pyqt-5.6.0-py36h0386399_5/lib/python3.6/site-packages/PyQt5
• /usr/lib64/qt5/plugins/PyQt5
• ~/anaconda3/lib/python3.6/site-packages/PyQt5

我试过前三种，但都不管用。更多信息：我安装了python-qt-devel来自fedora存储库。你知道吗

我错过了什么我应该做的？你知道吗
