NAME

       ecm-toolchains - ECM Toolchains Reference

INTRODUCTION

       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.

ALL MODULES

   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.
