 #### Prerequisites
 
 - Visual Studio 2019
-- Qt Visual Studio Tools
+- cmake
 - Qt Library
 
 #### Build steps
 
-Open the `sln` and build.
-
-#### Deployment steps for shared library
-
-The example here is for deploying an x64 Release build, but other build work analogously.
-
-Start a `x64 Native Tools Command Prompt for VS 2019`:
-
 ```console
-> cd %QTDIR%\msvc2019_64\bin
-> set PATH=%PATH%;%CD%
-> cd %DEV%\AdaptiveBrightness\AdaptiveBrightness
-> windeployqt --no-system-d3d-compiler ..\x64\Release\AdaptiveBrightness.exe
+> cmake -G "Visual Studio 16 2019" -A x64 -B build -DCMAKE_PREFIX_PATH="%QTDIR%\msvc2019_64\lib\cmake"
 ```
 
-#### Deployment steps for statically linked library
+Use the generated `*.sln` to build.
 
-Qt does not provide a statically built library, so this has to be built by hand. The Qt installer for Windows also installs the Qt sources which can be used to build the static library.
-
-The following batch script sets up the build environment for an x64 build:
-
-```batch
-REM Set up Microsoft Visual Studio 2017, where <arch> is amd64, x86, etc.
-CALL "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" amd64
-SET _ROOT=%QTDIR%\Src_x64
-SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH%
-REM Uncomment the below line when using a git checkout of the source repository
-REM SET PATH=%_ROOT%\qtrepotools\bin;%PATH%
-SET _ROOT=
-```
-
-Then navigate to the source directory and configure the build system:
-
-```console
-> configure -opensource -confirm-license -nomake examples -nomake tests -skip webengine -static -static-runtime -debug-and-release -mp -prefix %QTDIR%\msvc2019_64_static
-```
-
-And build and install:
-
-```console
-> nmake
-> nmake install
-```
+There is an additional build step that automatically copies all required DLLs into the output directory for easy deployment.
