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

cmake qt linux

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

The suffix "dev" stands for development packet.

Adding this option to cmake works for me in Kubuntu 18.04 :

-DQT_QMAKE_EXECUTABLE=qmake-qt4
