CMake can't find QtCore

Question

My project uses cmake which tried to look for QT4 which is installed:

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

Still I continue to get this error from cmake:

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.

Any pointers will be really helpful

Answer 1

You have probably not installed QT4 dev packets. On Ubuntu this is something like libqt4-dev.

The suffix "dev" stands for development packet.
