My conanfile:

def build(self):
cmake = CMake(self, generator='Xcode')
cmake.configure()
cmake.build()

If i removed “, generator=‘Xcode’” it works.

Hi,

I have installed cmake exactly 3.19.0:

cmake --version
cmake version 3.19.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Set the minimum to 3.19.

And it work:

make build-ios
rm -rf out/build-ios
mkdir -p out/build-ios
cd out/build-ios && \
		conan build ../../conan/recipe/conanfile.py \
		--source-folder ../../cmake \
