Qt-CMake-HelloWorld

A Simple Qt5 Program Built with CMake 3.8.2

Building

MinGW

From the command line, you'll probably have to tell CMake where to find Qt and to use MinGW instead of MSVC. You'll probably want something along the lines of:

>cmake -DCMAKE_PREFIX_PATH="path/to/Qt5/lib/cmake" -G"MinGW Makefiles" path/to/source

I have also successfully used Qt Creator with MinGW. Depending upon your setup, you may need to tell CMake where to find Qt. This can be done by adding -DCMAKE_PREFIX_PATH="path/to/Qt5/lib/cmake" to the arguments input box in the CMake Wizard.

Visual Studio

I usually use the CMake GUI with Visual Studio, but the command line also works. To get everything generated properly, you'll need to select the right generator and probably need to point CMAKE_PREFIX_PATH at the CMake files in the Qt install.

CMake GUI, Visual Studio 2015, Qt 5.9.1, 64 bit: Add a path entry called CMAKE_PREFIX_PATH and set the value to path/to/Qt5/lib/cmake. Configure and select the Visual Studio 14 2015 Win64 generator. Generate and you're done.

CMake Command Line, Visual Studio 2015, Qt 5.9.1, 64 bit: Run vcvarsall, then execute CMake in your build directory:

>cmake -DCMAKE_PREFIX_PATH="path/to/Qt5/lib/cmake" -G"Visual Studio 14 2015 Win64" path/to/source

Clang with Visual Studio

Newer versions of Clang and Visual Studio work pretty well together, and relatively little effort is required. After installing Clang (it may be required to add Clang to your path during the install).

CMake GUI, Visual Studio 2015, Clang 4.0.1, Qt 5.9.1, 64 bit: Add a path entry called CMAKE_PREFIX_PATH and set the value to path/to/Qt5/lib/cmake. Configure and select the Visual Studio 14 2015 Win64 generator with the toolset LLVM-vs2014 (yes, 2014). Generate and you're done.

CMake Command Line, Visual Studio 2015, Clang 4.0.1, Qt 5.9.1, 64 bit: Run vcvarsall, then execute CMake in your build directory:

>cmake -DCMAKE_PREFIX_PATH="path/to/Qt5/lib/cmake" -G"Visual Studio 14 2015 Win64" -T"LLVM-vs2014" path/to/source
