我一直试图将一个大型的C ++项目编译为wasm，该项目使用CMake构建该项目。我几乎没有CMake文件的经验，而且我已经在这场战斗中奋战了几个月。
[首先，我尝试通过this链接在我的机器上安装Webassembly编译器。我成功安装了它并运行了“ hello world”项目。但是，当尝试构建项目时，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）。
然后我尝试使用docker映像，并构建了以下Dockerfile：
FROM trzeci/emscripten AS builder

apt-get install -y build-essential \

但是出现相同的错误，缺少库。

我已经尝试跟踪this和this链接，但没有进行任何操作。有CMake / WebAssembly经验的人可以帮助我吗？
项目链接为this。 CMake文件太大，无法在此处发布...
编辑添加-DBoost_DEBUG=ON选项后的日志：

我遇到了同样的问题，我认为这与Emscripten问题有关：
https://github.com/emscripten-core/emscripten/issues/10078
[FindBoost.cmake调用find_path()以查找boost/config.hpp在许多备用路径中的位置（在HINTS，which is synonymous with PATHS中指定）]
显然，Emscripten中目前存在一个错误（我正在使用版本1.39.6），因为它不尊重PATHS / HINTS变量。
