• Polly Android: updates already in branch new.android
• Polly sanitize-address: use new RPATH functionality instead of old approach
• Update Hunter (CMake + documentation)
• Merge update various toolchains w/ -ffunction-sections -fdata-sections; add ios 10 toolchains ruslo/polly#104
• Drishti: ANDROID_NATIVE_API_LEVEL -> CMAKE_SYSTEM_VERSION

Probably need to change a few variables in those projects too:

• https://github.com/hunter-packages/android-apk
• https://github.com/hunter-packages/qt-android-cmake

This one is ready in general but it is a big move which may have hidden issues inside so I'm setting 0.3 milestone for now.

More variables coming:

• https://gitlab.kitware.com/cmake/cmake/merge_requests/254

Probably it's better to wait them release and avoid confusion.

Polly sanitize-address: use new RPATH functionality instead of old approach

Not the 3.7 feature. See ruslo/polly#113

Merge ruslo/polly#104

It is closed now... I copy/pasted osx-10-12-sanitize-address and osx-10-12-sanitize-address-hid-sections toolchains from your custom release:

• ruslo/polly@801131c
• ruslo/polly@a916583

we can use master in Drishti testing.
