ecm-toolchains - ECM Toolchains Reference
Extra CMake Modules (ECM) provides some toolchain modules. Unlike normal modules, these are not included directly in projects, but specified with the CMAKE_TOOLCHAIN_FILE cache variable on the commandline.
AndroidToolchain Enable easy compilation of cmake projects on Android. By using this android toolchain, the projects will be set up to compile the specified project targeting an Android platform, depending on its input. Furthermore, if desired, an APK can be directly generated by using the androiddeployqt tool. NOTE: This module requires CMake 3.1. Since 1.7.0. Usage To use this file, you need to set the CMAKE_TOOLCHAIN_FILE to point to AndroidToolchain.cmake on the command line: cmake -DCMAKE_TOOLCHAIN_FILE=/usr/share/ECM/toolchain/AndroidToolchain.cmake You will also need to provide the locations of the Android NDK and SDK. This can be done on the commandline or with environment variables; in either case the variable names are: ANDROID_NDK The NSK root path. ANDROID_SDK_ROOT The SSK root path. Additional options are specified as cache variables (eg: on the command line): ANDROID_ARCHITECTURE The architecture to compile for. Default: arm. ANDROID_TOOLCHAIN The toolchain to use. See the toolchains directory of the NDK. Default: arm-linux-androideabi. ANDROID_ABI The ABI to use. See the sources/cxx-stl/gnu-libstdc++/*/libs directories in the NDK. Default: armeabi-v7a. ANDROID_GCC_VERSION The GCC version to use. Default: 4.9. ANDROID_API_LEVEL The API level to require. Default: 14. ANDROID_SDK_BUILD_TOOLS_REVISION The build tools version to use. Default: 21.1.1. Deploying Qt Applications After building the application, you will need to generate an APK that can be deployed to an Android device. This module integrates androiddeployqt support to help with this for Qt-based projects. To enable this, set the QTANDROID_EXPORTED_TARGET variable to the target you wish to export as an APK, as well as ANDROID_APK_DIR to a directory containing some basic information. This will create a create-apk-<target> target that will generate the APK file. See the Qt on Android deployment documentation for more information. For example, you could do: cmake \ -DCMAKE_TOOLCHAIN_FILE=/usr/share/ECM/toolchain/AndroidToolchain.cmake \ -DQTANDROID_EXPORTED_TARGET=myapp \ -DANDROID_APK_DIR=myapp-apk make make create-apk-myapp The APK would then be found in myapp_build_apk/bin in the build directory.
