MSYS 編譯libjxl-0.11.1步驟

1. 下載libjxl-0.11.1.tar.gz
2. 解壓到libjxl-0.11.1目錄
3. libjxl-0.11.1目錄下創(chuàng)建build2目錄
4. 修改deps.sh文件，skcms下載地址已經(jīng)無效
    # download_github third_party/skcms \
    # "https://skia.googlesource.com/skcms/+archive/"
5. 直接下載skcms-b2e6926
    git config --global http.proxy 'socks5://127.0.0.1:10808' 
    git config --global https.proxy 'socks5://127.0.0.1:10808'
    git clone https://skia.googlesource.com/skcms
    cd skcms
    git checkout b2e692629c1fb19342517d7fb61f1cf83d075492
    
    或者直接下載b2e6926
    https://skia.googlesource.com/skcms/+archive/b2e692629c1fb19342517d7fb61f1cf83d075492.tar.gz
    
6. 下載的skcms源碼拷貝到libjxl-0.11.1/third_party/skcms
7. 進入build2目錄，運行../deps.sh，下載所有的third_party源碼
8. 如果系統(tǒng)已經(jīng)安裝過libjxl的其他版本，就把include/jxl目錄改名為include/jxl-xxx
   
9. 修改libjxl-0.11.1\third_party\skcms\skcms.cc文件,不修改編譯出錯   
        case CpuType::Baseline:
            break;
    }
    
    //run(program, context, ops - program, (const char*)src, (char*)dst, n, src_bpp,dst_bpp);
    return true;
    
10.然后運行cmake-gui（cmake的最新版本）
   根據(jù)自己要求配置完成后，make就可以。

如果靜態(tài)編譯ffmpeg時，需要修改jxl_export.h
define JXL_EXPORT __declspec(dllexport)  --->   define JXL_EXPORT
define JXL_EXPORT __declspec(dllimport)  --->   define JXL_EXPORT
