[ThorVG] Static linking on Windows fails with LNK2019

[tschnz]

Operating system

Windows 11 Pro (10.0.26100 Build 26100)

Compiler

MSVC 19.44.35208 64bit

Steps to reproduce the behavior

- Add `thorvg` and `pkgconf` to vcpkg.json
- `vcpkg install`
- Copy files for minimal example (attached)
- Configure with `cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE=...`
- Build and see LNK2019

Additional context

I'm just trying to build a minimal example on Win64 with static linking:

#include <thorvg.h>

int main() {
  tvg::Initializer::init(tvg::CanvasEngine::Sw, 0);
  return 0;
}

CMakeLists.txt vcpkg.json

Sorry, to reproduce you need to explicitly configure with static triplet

cmake -B build -G Ninja -DVCPKG_TARGET_TRIPLET=x64-windows-static -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE=...\vcpkg\scripts\buildsystems\vcpkg.cmake

Looks like TVG_STATIC wasn't set? If I put #define TVG_STATIC 1 before the ThorVG include it compiles and links
