Have to specify cppstd

[hmate9]

For me the build instructions did not work out of the box, but after git cloningwith all submodules this worked:

git clone --recurse-submodules https://github.com/neverlosecc/source2gen.git
conan build -o "game=DEADLOCK" --build=missing . -s compiler.cppstd=23

[es3n1n]

This is extremely weird if the error you were getting is the same as #83. What was the error you were getting exactly? Can you paste the whole output of all commands, both when it does not work and when it does?

[hmate9]

Here is the entire output from a fresh clone to using the current default conan build command, seeing it fail and then using with the -s compulter.cppstd=23 and having it succeed:

Oh that. Yeah, this isn't the same issue as I linked. It's fine though, thanks for reporting. This somewhat falls outside of the source2gen issues tbh, because for some reason your cppstandard was not the latest one your compiler actually supports, but I guess we can force it to be 23 anyways.
