我正在尝试从源代码修订版5.12.3为我的主机系统（Ubuntu 18.04 VM）构建qtconnectivity。当我尝试在项目文件上运行qmake时，出现此错误：
Project ERROR: Could not find feature bluez.
我安装了每个该死的bluez软件包，但是bluetoothd守护程序没有运行，我想是问题所在。这是我已安装的蓝牙相关软件包的列表：
udo apt list --installed | grep 'bluez\|bluetooth'

任何人都知道如何解决此错误？
通常，您需要安装-dev软件包才能在编译时使用库。
这里是qtconnectivity使用的测试：https://github.com/qt/qtconnectivity/blob/dev/config.tests/bluez/main.cpp。您需要一个包含bluetooth/bluetooth.h的软件包。
