macos/cmake/compile_features: no known features for CXX compiler

See original GitHub issue

Compiling a cmake project using the COMPILE_FEATURES property (eg c++11) on the macos image (clang 4.0.1) leads to this kind of error:

Here’s the minimal non-working example: https://github.com/jschueller/cmake-target_compile_features

is it specific to conda-forge ?

I ran in to this error with CMake 3.15, and – to avoid patching source – a different work-around is to tell CMake that the compiler has the requested feature(s):

-DCMAKE_CXX_COMPILE_FEATURES=cxx_constexpr

(it’s not clear to me if or why CMP0025 was disabled in my case, because CMake version was 3.15, and the package had set cmake_minimum_required(VERSION 3.1). CMake knows about upstream Clang versioning for other platforms, but perhaps on APPLE some logic is shunted toward AppleClang)

It’s not specific to conda-forge. CMake has issues with vanilla clang on MacOSX. Try changing the cmake_minimum_required line to 3.
