# During first run of cmake the toolchain file will be loaded twice,
# - /usr/share/cmake-3.23/Modules/CMakeDetermineSystem.cmake
# - /bld/CMakeFiles/3.23.2/CMakeSystem.cmake
#
# But once you already have non-empty cmake cache it will be loaded only
# once:
# - /bld/CMakeFiles/3.23.2/CMakeSystem.cmake
#
# This has no harm except for double load of toolchain will add
# --gcc-toolchain multiple times that will not allow ccache to reuse the
# cache.
