This project is based on the pretty old QMake2CMake that has been improved, fixed and updated to the latest version of QT.
In order to use build this, do the following:
git clone https://github.com/diegostamigni/qmake2cmake.git
cd qmake2cmake
mkdir build
cd build
CMAKE_PREFIX_PATH=<QT INSTALLATION DIR> cmake ..
make
The above steps will generate the binary in the build folder.
