# cmake 3.7 has a bug where add_custom_command() appends the target name as an
# argument if running an imported command. This breaks cross compiling for
# Windows because qt5_add_resources() calls add_custom_command() with the
# Qt5::rcc target.
#
# We'll work around this by unsetting CMAKE_CROSSCOMPILING_EMULATOR.
#
# See: https://gitlab.kitware.com/cmake/cmake/issues/16288
