[Solved] Build fail with undefned ffi references

[lqfjun88]

I try to manully compile Freecad from the latest github and have the following errors when I make:

/usr/bin/ld: /lib/x86_64-linux-gnu/libp11-kit.so.0: undefined reference to `ffi_closure_alloc@LIBFFI_CLOSURE_7.0'
/usr/bin/ld: /lib/x86_64-linux-gnu/libp11-kit.so.0: undefined reference to `ffi_type_uint8@LIBFFI_BASE_7.0'

I have installed libffi-dev on ubuntu 20.04 but i dont know why it fails to compile

Managed to solve this issue by making the following changes in 3 CMakeLists.txt by adding -lffi to link libffi library:

Replace CMakeLists.txt with the following files in the directory (remember to rename the files to CMakeLists.txt:
CMakeLists1.txt : tests/
CMakeLists2.txt : tests/src/Base
CMakeLists3.txt : src/Main
