This variable sets the toolchain location for the supported toolchains. It is required for the toolchain files provided with the Qt Quick Ultralite packages.

Note: The toolchain located in the given QUL_TARGET_TOOLCHAIN_DIR must match the toolchain specified in CMAKE_TOOLCHAIN_FILE.

This page uses QUL_ROOT and QUL_TOOLS in command line examples as if they were set as environment variables. For example:

export QUL_ROOT=$HOME/Qt/QtMCUs/2.7.1
export QUL_TOOLS=$HOME/Qt/Tools/QtMCUs
set QUL_ROOT=C:\Qt\QtMCUs\2.7.1
set QUL_TOOLS=C:\Qt\Tools\QtMCUs
