[NativeAOT] set StaticICULinking results in a CmakeLists.txt that violates policy CMP0000 of Cmake (affects CMake version >= 3.9.0) #93436
Description
Intro:
when compiling with NativeAOT and StaticICULinking flags, the resulting CmakeLists.txt does not respect policy CMP0000 of Cmake and produces a warning :
CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as
cmake_minimum_required(VERSION 3.22)
should be added at the top of the file.
steps to produce
1- create a new dotnet console project
2- add <StaticICULinking>true</StaticICULinking> <PublishAot>true</PublishAot> to .csproj file
3- add Microsoft.Dotnet.ILCompiler 8.0.0-rc.2.23479.6 nuget
4- run dotnet publish -r linux-x64 -c Release --self-contained
Expected Behavior
no warning should be emitted by Cmake
Actual Behavior
Cmake emits warning about policy CMP0000
Other Areas Effected ?
perhaps
System.IO.Compression.Native,
System.Security.Cryptography.Native,
System.Security.Cryptography.Native.Android,
System.Security.Cryptography.Native.Apple
...
Solution
myabe setting the min version of cmake to the version that reflects
https://github.com/dotnet/runtime/blob/main/src/coreclr/CMakeLists.txt
or
https://github.com/dotnet/runtime/blob/main/src/native/libs/CMakeLists.txt
Tested System
1- dotnet 8.0.100-rc.2.23502.2
2- cmake version 3.22.1 , This affects CMake version >= 3.9.0
