Highly improtant note: The installation directory should not contain any space or non-English character, otherwise weird error would happen when building. 

Open CMake 2.8.2, set the source and build directory:

Click "Configure", choose "MinGW Makefiles" and "Specify native compliers"

Set the C and C++ compiler from the Qt SDK

Don't forget to add the following to the system path:

C:\Qt\5.4\mingw491_32\bin

C:\Qt\Tools\mingw491_32\bin

Then click "Configure" and "Generate", then open cmd and go the build directory, and run "mingw32-make"

Highly important: You need to select "With_Qt" before click "Generate"!

When it is done, then run "mingw32-make install" and hit enter again
