I built sqlitebrowser in Ubuntu 14.04 and foud qmake could not exec when run cmake command.
$ cmake ..
qmake: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qmake': No such file or directory
CMake Error at /usr/share/cmake-2.8/Modules/FindQt4.cmake:1386 (message):
  Found unsuitable Qt version "" from NOTFOUND, this code requires Qt 4.x
Call Stack (most recent call first):
  libs/qhexedit/CMakeLists.txt:8 (find_package)
Saw that Ubuntu 14.04 has not qt4-qmake. So, just install qt-sdk to solve this error:

sudo apt-get install qt-sdk
