首先我克隆这个项目：https://github.com/yushi-bot/CGAL_triangulation_demo。
背景资料：我正在尝试使用Emscripten技术将使用CGAL库的C++程序编译为WebAssembly（wasm）格式，以便在网页上运行它。单独使用CMake时编译成功。但是，当我尝试使用命令emcmake make../时，编译过程失败。

cmake ../        (at build folder which make by myself , it is success)

个字符
当我使用这个命令时。

emcmake cmake ../

configure: cmake ../ -DCMAKE_TOOLCHAIN_FILE=/usr/share/emscripten/cmake/Modules/Platform/Emscripten.cmake -DCMAKE_CROSSCOMPILING_EMULATOR=/usr/bin/node;--experimental-wasm-threads
CMake Error at CMakeLists.txt:4 (find_package):
  By not providing "FindCGAL.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "CGAL", but
  CMake did not find one.

  Could not find a package configuration file provided by "CGAL" with any of
  the following names:

    CGALConfig.cmake
    cgal-config.cmake

  Add the installation prefix of "CGAL" to CMAKE_PREFIX_PATH or set
  "CGAL_DIR" to a directory containing one of the above files.  If "CGAL"
  provides a separate development package or SDK, be sure it has been
  installed.

的字符串
请告诉我怎么修。
多谢帮忙
