[nodejs/node] LIEF is built with two C++ standard version flags

### ROOT CAUSE The issue arises because LIEF is being built with two conflicting C++ standard version flags: `-std=gnu++20` and `-std=gnu++17`. This conflict can lead to undefined behavior and compilation errors because the compiler may not be able to resolve which standard to use for certain parts of the code. ### CODE FIX To resolve this issue, you should ensure that only one C++ standard version flag is used when building LIEF. Given that LIEF is a library that may need to support older versions of Node.js, it is advisable to use `-std=gnu++17` to maintain compatibility with a wider range of Node.js versions. Here is the fix: 1. **Modify the CMake configuration**: - Open the `CMakeLists.txt` file in the LIEF repository. - Locate the line where the C++ standard version is set. It might look something like this:

cmake
     set(CMAKE_CXX_STANDARD 20)
     set(CMAKE_CXX_STANDARD_REQUIRED ON)
     

   - Change it to use `-std=gnu++17`:
     
cmake
     set(CMAKE_CXX_STANDARD 17)
     set(CMAKE_CXX_STANDARD_REQUIRED ON)
     


2. **Rebuild LIEF**:
   - Run the CMake configuration and build process again to ensure that the changes take effect.

By making this change, you ensure that LIEF is built with a consistent C++ standard version, which should resolve the conflict and allow the build to proceed successfully.
