Compiling for iOS with CMake
Just use this toolchain file: http://code.google.com/p/ios-cmake/ and use it as
cmake -DCMAKE_TOOLCHAIN_FILE=path_to_your_toolchain_fileThen, in CMakeLists.txt:
SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -arch armv7")SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -arch armv7")
By following cmake-toolchains documentation I did like below:
cmake -G Xcode -B build \ -DCMAKE_SYSTEM_NAME=iOS \ -DCMAKE_Swift_COMPILER_FORCED=true \ -DCMAKE_OSX_DEPLOYMENT_TARGET=11.0Note: That assignment CMAKE_OSX_DEPLOYMENT_TARGET=11.0 is not a mistake when targeting iOS.
I've been using an updated version of the iOS CMake toolchain for quite a while: https://github.com/leetal/ios-cmake
This creates an Xcode project which you can drag into an existing iOS project if necessary.
I wrote a blog post with more details: https://blog.tomtasche.at/2019/05/how-to-include-cmake-project-in-xcode.html
