From 91d37a1381b77c12a1c99ea43f5b1bf464a0ff40 Mon Sep 17 00:00:00 2001 From: Alexandru Croitor Date: Wed, 23 Aug 2017 16:47:14 +0200 Subject: Streamline Qt5 detection on macOS This consists of a few things: - Remove the detection and usage of ALTERNATIVE_QT_INCLUDE_DIR in setup.py, because CMake takes care of finding the correct Qt include headers. - Add detection of framework / non-framework includes in the CMake rules, instead of in the setup.py script. - Don't pass QT_QMAKE_EXECUTABLE from setup.py to CMake, because it is not being used. It was previously used for detecting Qt4 via the CMake FindQt4.cmake file. Now it is done by find_package() which detects qmake from the environment. - Get rid of the old "/Library/Frameworks" QT_INCLUDE_DIR, which was where the official Qt 4.8.x packages installed Qt. - Deprecate usage of ALTERNATIVE_QT_INCLUDE_DIR. Now it is only used if CMake fails to detect the proper include headers of Qt5 (which should not happen).
