libftdi was FTBFS[1] in Fedora Rawhide after a GCC 9.0.X mass rebuild but
the problem turned out to be behavior changes[2] in CMake with regards to
SWIG[3].
The UseSWIG module will now use standard target names and not generate the
SWIG_MODULE_<target>_REAL_NAME variable.
I applied the following patch which appears to have solved the problem for
now.
$ cat libftdi-cmake_swig.patch
