# In `setup.py.in`, some dynamic libraries (eg, libxpuapi.so) are modified using
# patchelf. In rare cases, if the a linker is linking that dynamic library for
# some executables at the same time, a `file not recognized, file truncated`
# error may occur, result in the compilation error.
# So, add dependency to force the cpp tests built before running `setup.py.in`.
