Transfer the applicable NixOS patches as of 2018-01-19:
- Not adopted: We don't change the .cmake.in and .prf, but use config
mechanisms provided by th Qt build system.
- src/corelib/tools/qtimezoneprivate_tz.cpp: Adopted patch: Use $TZDIR to
search for time-zone data. Thus avoid depending on package "tzdata", which
often introduces changes with near-immediate effects, so it's important to
be able to update it fast.
- src/corelib/kernel/qcoreapplication.cpp: Not adopted: NixOS adds plugin
paths derived from PATH. We do not need this, since we already have
native-search-path QT_PLUGIN_PATH.
- src/network/kernel/qdnslookup_unix.cpp,
src/network/kernel/qhostinfo_unix.cpp: Transferred: Use hard-coded path to
libresolv.
- src/network/ssl/qsslcontext_openssl.cpp: Not adopted: NixOS changes a
conditional compilation for Qt 5.9 (but leaves it unchanged for Qt 5.10) to
fix compilation with libressl. But Qt does not support libressl anway, see
config.tests/openssl/openssl.cpp in qtbase 5.9.4.
- src/plugins/platforminputcontexts/compose/generator/qtablegenerator.cpp:
Transferred: Use hard-coded path to libx11.
- src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp:
Transferred: Use hard-coded path to mess's libGL, no need for a fall-back.
- src/plugins/platforms/xcb/qxcbcursor.cpp: Transferred: Use hard-coded path
to Xcursor.
- src/plugins/platformthemes/gtk3/main.cpp: Not adopted: NixOS changes
$XDG_DATA_DIRS and $GIO_EXTRA_MODULES in the code. We already have a
search-path-specification for this.
- src/testlib/qtestassert.h: Decided not to adopt this for guix.
