[flang-dev] CMake standalone and compile flags

[David Truby via flang-dev]

Hi Mehdi,

That branch enables out of tree builds; I believe there are people that still rely on those which is why we added that branch in when rewriting the CMake infrastructure.
There's an open review to fix a similar issue as is reported in the discussion you linked but it seems to have stalled on a discussion about whether to continue to force Werror on, perhaps you could take a look at that and comment there if it fixes this issue or not?

The review is at https://reviews.llvm.org/D78306

Thanks
David Truby

Subject: [flang-dev] CMake standalone and compile flags

Hi,

I was looking into fixing this error that someone has when building flang: https://llvm.discourse.group/t/error-when-building-with-cmake/935

Then I noticed that flang/CMakeLists.txt still has this branch: https://github.com/llvm/llvm-project/blob/master/flang/CMakeLists.txt#L42 ; is there anyone that relies on it or can we simplify this file and the way the options are setup?

Thanks,
