# We want the same build type to be used when configuring all Qt repos or standalone
# tests or single tests.
# To do that, we need to force-set the CMAKE_BUILD_TYPE cache var because CMake itself
# initializes it with the value of CMAKE_BUILD_TYPE_INIT at the start of project
# configuration, so we need to override it.
# Note the value of CMAKE_BUILD_TYPE_INIT is different based on the platform, most
# Linux and macOS platforms will have it empty, but Windows platforms will have a value.
#
# We can't reliably differentiate between a value set on the command line by the user
# and one set by CMake, so we use a few heuristics:
# 1) When using a qt.toolchain.cmake file, we rely on the toolchain file to tell us
#    if a value was set by the user at initial configure time. On a 2nd run there will
#    always be a value in the cache, but at that point we've already set it to whatever it needs
#    to be.
# 2) If a toolchain file is not used, we rely on the value of the CMake internal
#    CMAKE_BUILD_TYPE_INIT variable.
#    This won't work reliably on Windows where CMAKE_BUILD_TYPE_INIT is non-empty.
#
# Both cases won't handle an empty "" config set by the user, but we claim that's an
# unsupported config when building Qt.
#
# Allow an opt out when QT_NO_FORCE_SET_CMAKE_BUILD_TYPE is set.
# Finally, don't set the variable if a multi-config generator is used. This can happen
# when qtbase is built with a single config, but a test is built with a multi-config generator.
