CMake cannot detect swift compiler in OS Ventura

Usage
1

Hi, I’m working on macOS and have updated my OS version recently. when I try to build swift based library generated from cmake, I fail on the following line

enable_language(Swift)

since the compiler couldn’t be found (although I’ve properly installed Xcode+developer tools)
Here’s the relevant output

-- The Swift compiler identification is unknown
-- Configuring incomplete, errors occurred!
See also "/Users/me/myProj/CMakeFiles/CMakeOutput.log".
See also "/Users/me/myProj/CMakeFiles/CMakeError.log".
CMake Error at CMakeLists.txt:17 (enable_language):
No CMAKE_Swift_COMPILER could be found

Here’s my swift compiler location

❯ xcrun swift -version
Apple Swift version 5.7.2 (swiftlang-5.7.2.135.5 clang-1400.0.29.51)
Target: arm64-apple-darwin22.2.0
❯ xcrun --find swift
/Library/Developer/CommandLineTools/usr/bin/swift

Perhaps there’s a way to explicitly set the compiler pointer ?

Thanks !

Can you attach the contents of the CMakeOutput.log and CMakeError.log files mentioned in your output?

Also make sure you’ve started up the Xcode IDE at least once after you updated. I vaguely recall sometimes needing to accept a license or install additional components in the past and this affected the ability of command line tools being able to build things.

Thanks! Running the xcode UI for the first time fixed the unknown compiler issue.
