CMake找不到QtCore

Question

我的项目使用cmake，它试图查找已安装的QT4：

root@netqa1:~# which qmake
/usr/bin/qmake

root@netqa1:~# ls -l /usr/lib/i386-linux-gnu/libQtCore.so*
lrwxrwxrwx 1 root root      18 Feb  6  2013 /usr/lib/i386-linux-gnu/libQtCore.so -> libQtCore.so.4.8.1
lrwxrwxrwx 1 root root      18 Feb  6  2013 /usr/lib/i386-linux-gnu/libQtCore.so.4 -> libQtCore.so.4.8.1
lrwxrwxrwx 1 root root      18 Feb  6  2013 /usr/lib/i386-linux-gnu/libQtCore.so.4.8 -> libQtCore.so.4.8.1
-rw-r--r-- 1 root root 2998336 Feb  6  2013 /usr/lib/i386-linux-gnu/libQtCore.so.4.8.1

尽管如此，我仍然从cmake得到这个错误：

Warning: QT_QMAKE_EXECUTABLE reported QT_INSTALL_LIBS as /usr/lib/i386-linux-gnu
Warning: But QtCore couldn't be found.  Qt must NOT be installed correctly, or it wasn't found for cross compiling.

任何指点都会很有帮助

Answer 1

您可能尚未安装QT4开发包。在Ubuntu上，这有点像libqt4-dev。

后缀"dev“代表开发包。

Answer 2

在Kubuntu18.04中，将此选项添加到cmake中对我有效：

-DQT_QMAKE_EXECUTABLE=qmake-qt4
