Version Error while building KDE frameworks and Qt5

Hello Everyone.
For building Elisa from kdesrc-build, I am building the dependencies from
here:
<a href="https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Install_the_dependencies" title="https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Install_the_dependencies">https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Instal...</a>

But this is installing version 5.9.5 for Qt and version 5.44 for all kde
frameworks. Elisa requires versions 5.10.0 and 5.45 respectively. How can I
install these versions? I would be really grateful if someone can help me
out since I have spent a lot of time building the dependencies but its
resulting in errors while building elisa.
