LibOQS CMake fails with cmake 3.28.3

[wpj3799]

CMake of liboqs fails on Kali Linux VM images and Kali Linux WSL

On a clean image I ran: 1) sudo apt install astyle cmake gcc ninja-build libssl-dev python3-pytest python3-pytest-xdist unzip xsltproc doxygen graphviz python3-yaml valgrind libgmp3-dev git libssl-dev 2) git clone https://github.com/open-quantum-safe/liboqs.git 3) cd liboqs 4) cmake -GNinja -DOQS_USE_OPENSSL=ON -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=/usr

It throws this error which I don't understand since it finds the library v3.1.5?: CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases.

Environment:

• WSL: Linux 4.4.0-19041-Microsoft #3996-Microsoft x86_64 GNU/Linux
• Kali VM: Linux 6.6.9-amd64 Kali 6.6.9-1kali1 x86_64 GNU/Linux
• liboqs main branch
• which make -> /urs/bin/cmake
• cmake v.3.28.3

Not sure if this is a bug or a Kali issue but, any help would be appreciated.

Thanks for the bug report!

This appears to be a regression in CMake. I reproduced your error in a kali-rolling image with CMake 3.28.3. Everything worked fine, however, with CMake 3.25.1.

It's probably worth bringing this to the attention of the CMake team. For now, the following command worked for me with CMake 3.28.3:

cmake -GNinja -DOQS_USE_OPENSSL=ON -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=/usr -DOPENSSL_ROOT_DIR=/usr/lib/x86_64-linux-gnu

Please let me know if that works for you.

Yes, that seems to have worked. Thank you.

The same problem occurs in Ubuntu 24. I'm afraid we need to provide a workaround in OQS if we want to support that LTS release.
