# All my PKGBUILDs are managed at https://github.com/Martchus/PKGBUILDs where
# you also find the URL of a binary repository.

# All patches are managed at https://github.com/Martchus/qtbase

# There are different variants of the package which can be selected by simply adjusting pkgname:
# - mingw-w64-qt5-base or mingw-w64-qt5-base-opengl: using native OpenGL
# - mingw-w64-qt5-base-angle: using ANGLE rather than native OpenGL
# - mingw-w64-qt5-base-dynamic: allows choosing between ANGLE and native OpenGL dynamically at runtime
# - mingw-w64-qt5-base-noopenql: no OpenGL support
# The variants are conflicting (and hence can not be installed at the same time).
# See also: http://doc.qt.io/qt-5/windows-requirements.html#dynamically-loading-graphics-drivers

# The variants listed above only contain dynamic libraries. For building static libraries
# just append '-static' to the package name, eg. mingw-w64-qt5-base-static or mingw-w64-qt5-base-angle-static.
# The static variants rely on the corresponding dynamic variant for headers and tools.
# I only tested the static version using native OpenGL so far (mingw-w64-qt5-base-static).
# Note that ANGLE will still be loaded as dynamic library in mingw-w64-qt5-base-dynamic-static.

# By default CMake and qmake will link against the dynamic Qt libraries.

# To use the static Qt libraries with CMake prefix the Qt module with Static:
#  eg. find_package(Qt5Core) becomes find_package(StaticQt5Core)
# To use a static module, add the corresponding imported target, eg.
#  target_link_libraries(target ... Qt5::static::Core)
# This approach allows installing dynamic and static Qt in the same prefix and using
# both variants in the same CMake project.

# To use a static plugin, add the corresponding imported target, eg.
#  target_link_libraries(target ... Qt5::static::QWindowsIntegrationPlugin)
# Automatically importing static plugins is currently not possible, though. Hence it is required to use Q_IMPORT_PLUGIN, eg.
#  #include<QtPlugin>
#  Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin)

# To use the static Qt libraries with qmake set the following variables (either inside the *.pro file or as qmake argument):
#  CONFIG+=static

# Further Qt modules (those not found in the base repository and hence not included in this package) include by default
# static and dynamic libraries; if only one version is requried, just set $NO_STATIC_LIBS or $NO_SHARED_LIBS when building
# the package.

# By default, executables will not be removed because I find them useful when testing. To remove executables
# set $NO_EXECUTABLES (or $NO_STATIC_EXECUTABLES to remove statically linked executables only) when building the package.
# If Qt modules containing tools are built as static and as dynamic library only the dynamically linked tools will be present
# in the package.

# Qt packages can be built in the following order (for example):
#  qt5-base qt5-base-static qt5-declarative qt5-tools qt5-xmlpatterns qt5-script qt5-location qt5-multimedia qt5-sensors qt5-webchannel qt5-3d qt5-imageformats qt5-quickcontrols qt5-quickcontrols2 qt5-translations qt5-svg qt5-websockets qt5-winextras qt5-serialport qt5-canvas3d qt5-connectivity qt5-charts qt5-gamepad qt5-scxml qt5-datavis3s qt5-virtualkeyboard qt5-activeqt qt5-webkit
