TI'SDK is generated using Yocto/OpenEmbedded which allows the creation
of both Qt Embedded _and_ Qt for Xorg librairies. In order to make
the difference between both libraries which may both be integrated in
the same SDK, the Qt Embedded libraries have the 'E' suffix and the
SDK provides the right config files to make qmake happy.
So if you generate a rootfs using buildroot, you need to compile the
examples with buildroot's toolchain to have a consistent library naming.

Best regards,
