我知道我需要 zlib、libpng、libjpeg-turbo 和 yasm。
我已经成功构建并正确安装（希望如此），因为当我尝试在 Makefile 中使用以下配置“制作”libbpg 时：
# Enable compilation of Javascript decoder with Emscripten
#USE_EMCC=y
# Enable x265 for the encoder
USE_X265=y
# Enable the JCTVC code (best quality but slow) for the encoder
USE_JCTVC=y
# Compile bpgview (SDL and SDL_image libraries needed)
#USE_BPGVIEW=y
# Enable it to use bit depths > 12 (need more tests to validate encoder)
USE_JCTVC_HIGH_BIT_DEPTH=y
# Enable the cross compilation for Windows
CONFIG_WIN32=y
# Enable for compilation on MacOS X
#CONFIG_APPLE=y
在构建“bpgdec.exe”和 H265 编码器时，我没有在终端输出中看到任何严重错误。
但是，当涉及到 jctvc 时，我收到了一个很大的错误消息（大部分几乎是重复的）

（举个例子）
我注意到 linux 上的 Mingw-w64 使用的是 gcc 版本，其异常处理是 dw2 而不是 sjlj，根据上面的输出，这是 jctvc 所必需的。
我试图将 libgcc_s_sjlj_1.dll 移动到 /usr/x86_64-w64-mingw32/bin 和 /usr/x86_64-w64-mingw32/lib，但它不起作用。
我知道gcc可以配置启用sjlj，但这意味着我必须修改mingw-w64，这是我不敢的。
我的环境：在“apt update&&apt upgrade”之后新安装的 debian 10。所有最新的 zlib、libjpeg-turbo、libpng、mingw-w64、libbpg 源代码。
所以我想知道是否有人知道在 libbpg 中编译 jctvc 的正确方法。非常感谢。
