Summary: This is needed for NDK headers to work correctly, and is the same as the CMake code in the NDK does. Reviewers: #build_system, apol Reviewed By: apol Subscribers: apol, #frameworks Tags: #frameworks, #build_system Differential Revision: https://phabricator.kde.org/D10777
Summary: The prefix for the command is i686-linux-android, while the toolchain is x86 in this case. On ARM both values are the same. Reviewers: #build_system, apol Reviewed By: apol Subscribers: #frameworks Tags: #frameworks, #build_system Differential Revision: https://phabricator.kde.org/D10625
Summary: Those affect policy propagation and search path order for relative includes in CMake code, none of which is needed here. This silences a ton of warnings with CMake 3.10.

Summary: ANDROID_TOOLCHAIN is "x86" there, while the include path we want is "i686-linux-android". ANDROID_COMPILER_PREFIX has that value in all cases (for ARM both are the same, so nothing changes there).

Summary: For ARM it's not necessary, but when building for a x86 tablet I had to set ANDROID_TOOLCHAIN=x86 while gcc/g++ are prefixed with i686-linux-android. i.e. the path is android-ndk-r10e/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/i686-linux-android-g++ Test Plan: cmake picks up the right compiler for me now Reviewers: apol, mart Reviewed By: apol Subscribers: #build_system, #frameworks Tags: #frameworks, #build_system Differential Revision: https://phabricator.kde.org/D10462

Summary: We were using a link.txt file that cmake used to generate, on newer cmake versions it doesn't anymore. Instead use readelf, much like androiddeployqt does, to extract the depenencies. Catch: It relies on having all the binaries being at the same subdirectory, which is the default in ECM since not long ago.
