使用 CMake for ios 目标制作 C/C++ 项目静态库

Question

我正在使用 make 工具进行构建，对于 gdal 库，我可以使用以下命令进行配置。

cmake .. -G Xcode \                                                   
-DCMAKE_TOOLCHAIN_FILE=../ios-cmake/ios.toolchain.cmake \
-DPLATFORM=OS64COMBINED \
-DENABLE_BITCODE=1 \
-DCMAKE_INSTALL_PREFIX=../install \
-DPROJ_LIBRARY=/opt/homebrew/opt/proj/lib/libproj.a \
-DPROJ_INCLUDE_DIR=/opt/homebrew/opt/proj/include \
-DCRYPTOPP_LIBRARY=/opt/homebrew/opt/cryptopp/lib/libcryptopp.a \
-DCRYPTOPP_INCLUDE_DIR=/opt/homebrew/opt/cryptopp/include \
-DXercesC_LIBRARY=/opt/homebrew/opt/xerces-c/lib/libxerces-c.a \
-DXercesC_INCLUDE_DIR=/opt/homebrew/opt/xerces-c/include \
-DBUILD_APPS=OFF \
-DBUILD_PYTHON_BINDINGS=OFF \
-DWITH_GDAL_TOOLS=OFF \
-DLIBKML_INCLUDE_DIR=/opt/homebrew/Cellar/libkml/1.3.0_1/include \
-DLIBKML_LIBRARY_DIR=/opt/homebrew/Cellar/libkml/1.3.0_1/lib/libkml.a \
-DBOOST_INCLUDE_DIR=/opt/homebrew/Cellar/boost/1.86.0_2/include \
-DBOOST_LIBRARY_DIR=/opt/homebrew/Cellar/boost/1.86.0_2/lib

它成功配置了项目，但在使用“cmake --build . --config Release”进行构建时总是失败。

查看gdal文档，似乎没有提供

BOOST_INCLUDE_DIR

CMake通用配置选项。因此，将其添加到 cmake 命令可能不会执行任何包含头文件的操作。相反，文档说：

Similarly, recent versions of Homebrew no longer bundle Boost with libkml, 
causing a failure to find Boost headers. You should either install Boost 
manually or disable libkml when building on MacOS:

cmake -DGDAL_USE_LIBKML=OFF ..

那么在cmake过程的cmake配置步骤中是否有任何警告或提及boost，是否找到了手动安装的版本？

手动安装 boost 后（或找到现有的

BoostConfig.cmake

文件），您可以使用 cmake 选项

-Boost_DIR

指向它。
