From b0e5eee2964cbb79b8e290bf63ede041f593489b Mon Sep 17 00:00:00 2001 From: Iikka Eklund Date: Fri, 15 Jan 2021 15:32:19 +0200 Subject: [PATCH] Add conanfile.py to support builds with Conan Support building with Conan against Qt6 base binary package. The build recipe expects to locate QT_PATH from env. The 'qt-cmake(.bat)' is used for the build. 'CMAKE_TOOLCHAIN_FILE' is used to pick the toolchain file for cross compilations. For Android builds 'ANDROID_SDK_ROOT' and 'ANDROID_NDK_ROOT' need to be passed from env.
