 # QtCMake
-A CMake project for easy Qt connection to other CMake projects
+A C++ project template with Qt6 and CMake that downloads and compiles Qt.
+The resulting app is an executable that can be run on a system without Qt.
+
+The main Qt6 configuration is found in the [correspondent](lib/qt/CMakeLists.txt) CMakeLists.txt file.
+
+> Note: Although the project has CI compilation tests, they somehow only succeed on macOS.
+> I don't know why.
+> I tested manually on Windows and Linux, and it works perfectly.
+
+> Note that statically compiled Qt6 weights more than 5 GB.
+> The good thing is that user does not need whole compiled Qt6 with this configuration.
+
+## Prerequisites
+
+* CMake
+* Ninja
+* Git
+
+On Linux: most of the libraries that match `*xcb*` and `*xkb*` are required.
+
+## How to build and run
+
+Run the following commands from the project directory.
+
+1. Create CMake cache
+
+This step may take a lot of time because it downloads and compiles Qt.
+
+```shell
+cmake -S . -B cmake-build -G "Ninja" -DCMAKE_BUILD_TYPE=Release
+```
+
+2. Build executable target
+
+```shell
+cmake --build cmake-build --target QtCMake
+```
+
+3. Run executable target
+
+* On Windows:
+
+```shell
+.\cmake-build\bin\QtCMake.exe
+```
+
+* On *nix:
+
+```shell
+./cmake-build/bin/QtCMake
+```
