CMake找不到QtCore

我的项目使用cmake试图寻找安装的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

我还是继续从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.

任何指针都会非常有用
