# By default, FooConfigVersion is tied to architecture that it was
# generated on. Because Catch2 is header-only, it is arch-independent
# and thus Catch2ConfigVersion should not be tied to the architecture
# it was generated on.

# CMake does not provide a direct customization point for this in
# `write_basic_package_version_file`, but it can be accomplished
# indirectly by temporarily undefining `CMAKE_SIZEOF_VOID_P`.
