Prerequisites

To build this project from source, you will need:

• CMake (version 3.16 or higher)
• C Compiler: MinGW-w64 (GCC) or Microsoft Visual Studio (MSVC)

Building

Option 1: Building with CMake (Recommended)

• Using MinGW / GCC:

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

The compiled binary will be placed in the ./build/ directory.

• Using Visual Studio (MSVC):

cmake -B build
cmake --build build --config Release

The compiled binary will be placed in the ./build/Debug/ directory.

Option 2: Building with Just

You can use just recipes to quickly manage builds:

• Build with CMake (Release):

just cmake-build

• Direct GCC Release Build:

just compile-release

• Test Run

just test-compile-run

Option 3: Direct Compilation via GCC / MinGW

If you prefer compiling directly using GCC without CMake:

1. Compile the resource file:

windres ./resource.rc -O coff -o ./bin/resource.o

2. Compile and link the executable:

gcc -O3 -s -flto -mwindows ./src/window_fx.c ./bin/resource.o -o ./bin/window_fx.exe -lkernel32 -lcomctl32 -lgdi32 -lole32 -luser32 -lshlwapi -lshell32 -ldwmapi

Runtime

Access settings and options by right-clicking the application icon in the system tray.
