[Interest] Qt6 - Fails to compile when openssl-linked enabled

Marten,

Tried again without success. Maybe it's the directory layout. I don’t know I’m in the dark since the the CMakeOutput.log and CMakeError.log do not even mention ssl anywhere. Below is the new configure call:

./configure -prefix /Users/nsantos/Qt/6.4.2/macos -static -debug-and-release -nomake examples -nomake tests -nomake benchmarks -nomake manual-tests -nomake minimal-static-tests -openssl-linked -DOPENSSL_ROOT_DIR="/Users/nsantos/Qt-Utils/openssl" -DOPENSSL_USE_STATIC_LIBS

Where:

> find /Users/nsantos/Qt-Utils/openssl

gives:

/Users/nsantos/Qt-Utils/openssl
/Users/nsantos/Qt-Utils/openssl/include
/Users/nsantos/Qt-Utils/openssl/include/crypto
/Users/nsantos/Qt-Utils/openssl/include/crypto/md32_common.h
…
/Users/nsantos/Qt-Utils/openssl/lib
/Users/nsantos/Qt-Utils/openssl/lib/libcrypto.a
/Users/nsantos/Qt-Utils/openssl/lib/libssl.a

Where can I find more information?

Thank you!

Best regards,

Nuno
