Tengo un problema con la instalación: cuando quiero compilar KeePassX, cmakeaparece un error con QtCore. Intenté instalar libqtcore y obtuve E: Unable to locate package libqt4-core
el resultado de compilar KeePassX:

Busqué un poco en Google sobre esto hoy y encontré estos tres comandos, sin embargo, no sé cómo escribirlos exactamente:

export QTDIR="/path/to/qt-5.0.1"
export PATH="${QTDIR}/bin:${PATH}"

Existe esta variable que podría resultar útil cuando se trabaja con cmake:

export CMAKE_PREFIX_PATH="${QTDIR}"

Agrega la ruta a Qt a la ruta de búsqueda de Cmake.

Intente instalar libqt4-dev para instalar los archivos de desarrollo de Qt4.
