Xcode 12.2 iOS SDK 14.2 CMake 3.19.1

have tried both default magnum toolchain and polly toolchain.

with magnum default toolchain:

Hi, the 

Could NOT find Corrade (missing: CORRADE_INCLUDE_DIR
_CORRADE_CONFIGURE_FILE)

is one of the "usual crosscompiling issues" that CMake suffers from. Did you try with -DCMAKE_FIND_ROOT_PATH=/Users/jjj/workspace/ios-libs as I suggested on Gitter? That usually helps.

I have no idea what the Polly toolchain does, looks like it ignored the iOS installation altogether and found the native Corrade/Magnum in /usr/local instead, which is just wrong.

With -DCMAKE_FIND_ROOT_PATH=/Users/jjj/workspace/ios-libs i got the same error:

:eyes:

Stupid question, but ... /Users/jjj/workspace/ios-libs/include/Corrade/configure.h exists, right? This worked for building Magnum, right? There has to be something different between how you built Magnum and this which causes the error.

Oh my fault, have not checked that. So ~ not parsed correctly in zsh, the Corrade i built was not installed in ~/workspace/ios-libs. absolute path should be used.

The correct script i'm using:

Soo ... you ended up with a folder literally named ~? :sweat_smile: If that's so, I'm happy with my Bash and don't ever want to use anything else, haha :)
