Building

Requirements

• CMake 3.10+
• Vulkan SDK
• GLFW 3

Linux: install vulkan-devel (or equivalent) and libglfw3-dev from your package manager.

Windows: set the GLFW environment variable to your GLFW SDK root (e.g. C:\glfw-3.4.WIN64) and make sure VULKAN_SDK is set by the Vulkan SDK installer.

1 — Build blukpast

git clone https://github.com/wypifu/blukpast
cd blukpast
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)

2 — Build BkpView

git clone https://github.com/wypifu/bkpview
cd bkpview
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DBKP_ROOT=../../blukpast
make -j$(nproc)

If blukpast and bkpview share the same parent directory, -DBKP_ROOT can be omitted — CMake will find it automatically.
