Build fails on Ubuntu Saucy

[mechanical-snail]

Following the build instructions in the README, I ran:

$ git clone 'https://github.com/simgunz/redshift-plasmoid'
$ sudo aptitude install build-essential cmake kde-workspace-dev redshift
$ cd redshift-plasmoid/
$ mkdir build && cd build
$ cmake -DCMAKE_INSTALL_PREFIX=$(kde4-config --prefix) ..

which fails with the output:

Try to compile it with this command:

cmake -DQT_QMAKE_EXECUTABLE=/usr/bin/qmake-qt4 -DCMAKE_INSTALL_PREFIX=$(kde4-config --prefix) ..

[mechanical-snail]

That command works, and make builds it successfully. It it because it was trying to build with Qt5?

We should add a note to the readme.

[simgunz]

Yes the problem is Qt5. I'll update the readme.
