# This function is used to define a "Qt tool", such as moc, uic or rcc.
|
|
#
|
|
# USER_FACING can be passed to mark the tool as a program that is supposed to be
|
|
# started directly by users.
|
|
#
|
|
# We must pass this function a target name obtained from
|
|
# qt_get_tool_target_name like this:
|
|
# qt_get_tool_target_name(target_name my_tool)
|
|
# qt_internal_add_tool(${target_name})
|
|
#
|
|
# Option Arguments:
|
|
# INSTALL_VERSIONED_LINK
|
|
# Prefix build only. On installation, create a versioned hard-link of the installed file.
|
|
# E.g. create a link of "bin/qmake6" to "bin/qmake".
|
|
#
|
|
# One-value Arguments:
|
|
# EXTRA_CMAKE_FILES
|
|
# List of additional CMake files that will be installed alongside the tool's exported CMake
|
|
# files.
|
|
# EXTRA_CMAKE_INCLUDES
|
|
# List of files that will be included in the Qt6${module}Tools.cmake file.
|
|
# Also see TOOLS_TARGET.
|
|
# INSTALL_DIR
|
|
# Takes a path, relative to the install prefix, like INSTALL_LIBEXECDIR.
|
|
# If this argument is omitted, the default is INSTALL_BINDIR.
|
|
# TOOLS_TARGET
|
|
# Specifies the module this tool belongs to. The module's Qt6${module}Tools.cmake file
|
|
# will then contain targets for this tool.
|
|
# CORE_LIBRARY
|
|
# The argument accepts 'Bootstrap' or 'None' values. If the argument value is set to
|
|
# 'Bootstrap' the Qt::Bootstrap library is linked to the executable instead of Qt::Core.
|
|
# The 'None' value points that core library is not necessary and avoids linking neither
|
|
# Qt::Core or Qt::Bootstrap libraries. Otherwise the Qt::Core library will be publicly
|
|
# linked to the executable target by default.
