On my system, the following error message shown up when compiling
acs_py_enclave.c
`

`
My finding is the following script snippet that didn't detect the dependency
correctly in file `CMakeLists.txt`, because the package `pypy` also put some
header files e.g. `pypy_decl.h` in this folder so we cannot safely say that the
`pypy_dev` has got installed if the folder `/usr/lib/pypy/include` exists.
`
if(NOT EXISTS "/usr/lib/pypy/include")
message(
FATAL_ERROR
"pypy development package not found\nFor Ubuntu, please run `apt-get
install pypy-dev`"
)
endif()
