我一直试图编译一个大型C++项目，该项目使用CMake构建该项目，并将其编译为wasm。我几乎没有使用CMake文件的经验，而且我已经打了好几个月的仗了。

首先，我试着在我的机器上安装W组件编译器，遵循这链接。我成功地安装了它，并运行了"hello world“项目。但是当A试图构建该项目时，将cmake和make命令更改为emcmake和emmake，但它开始抱怨缺少依赖库(boost和lua)。

然后，我尝试了一个码头映像，并构建了以下Dockerfile

代码语言：javascript
运行
复制
FROM trzeci/emscripten AS builder

RUN apt-get update && \
 apt-get install -y build-essential \
    cmake \
    git-core \
    libboost-atomic-dev \
    libboost-chrono-dev \
    libboost-date-time-dev \
    libboost-filesystem-dev \
    libboost-system-dev \
    libboost-thread-dev \
    libglew-dev \
    liblua5.1-0-dev \
    libncurses5-dev \
    libopenal-dev \
    libssl-dev \
    libvorbis-dev \
    mercurial \
    zlib1g-dev && \
 apt-get clean && apt-get autoclean

WORKDIR /
RUN hg clone -r stable-3.0 http://hg.icculus.org/icculus/physfs/
WORKDIR /physfs/build/
RUN cmake ..
RUN make -j$(nproc)
RUN make install

COPY ./src/ /otclient/src/.
COPY CMakeLists.txt /otclient/.
WORKDIR /otclient/build/
RUN emconfigure cmake -DCMAKE_CXX_LINK_FLAGS=-no-pie -DCMAKE_BUILD_TYPE=Release -DEMSCRIPTEN_GENERATE_BITCODE_STATIC_LIBRARIES=1 ..
RUN make -j$(nproc)

FROM trzeci/emscripten
RUN apt-get update; \
  apt-get install -y \
    libglew2.0 \
    libopenal1; \
  apt-get clean && apt-get autoclean
COPY --from=builder /otclient/build/otclient /otclient/bin/otclient
COPY ./data/ /otclient/data/.
COPY ./mods/ /otclient/mods/.
COPY ./modules/ /otclient/modules/.
COPY ./init.lua /otclient/.
WORKDIR /otclient
EXPOSE 8080:8080
RUN npm install http-server -g
CMD ["http-server", "./bin/", "-p", "8080"]

但同样的错误出现了，缺少了库。

我已经试着跟踪这和这链接了，什么都没有。有CMake/WebAssembly经验的人能帮我吗？

项目链接是这。CMake文件太大了不能在这里发布..。

在添加-DBoost_DEBUG=ON选项后编辑日志：

我遇到了同样的问题，我认为这与这个“征文”问题有关：

https://github.com/emscripten-core/emscripten/issues/10078

FindBoost.cmake调用find_path()来查找boost/config.hpp在许多可选路径中的位置(在HINTS、它是路径的同义词中指定)

显然，目前在Emscripten (我使用的是1.39.6版本)中存在一个bug，因为它不尊重PATHS/HINTS变量。
