In case when qmake-qt4 does not exist, try using `qmake` but make sure it is indeed from the Qt 4 installation.
Alternatively, you might want to load `goldendict.pro` file from within Qt Creator, especially on Windows.
### Building with Chinese conversion support
To add Chinese conversion support you need at first install libopencc-dev package:
sudo apt-get install libopencc-dev
Then pass `"CONFIG+=chinese_conversion_support"` to `qmake`
qmake "CONFIG+=chinese_conversion_support"
### Building with Zim dictionaries support
To add Zim and Slob formats support you need at first install lzma-dev package:
sudo apt-get liblzma-dev
sudo apt-get install liblzma-dev
Then pass `"CONFIG+=zim_support"` to `qmake`
