Add portable CI workflow without MKL dependency - #32
Merged
Conversation
Add a second CI workflow that builds and tests the BLAS-free portable kernels without Intel MKL, so the -DCQR_WITH_MKL=OFF path stays healthy and gives fast feedback without the heavy libmkl-dev install. Configures with -DCQR_WITH_MKL=OFF in RelWithDebInfo, then builds and runs the four portable CTest suites across the gcc and clang matrix.

CMake, Ninja, GCC, and Clang all ship on the ubuntu-latest runner image, and the -DCQR_WITH_MKL=OFF build needs nothing beyond a C++17 compiler. Remove the apt install step entirely so the BLAS-free smoke check skips both the toolchain and the libmkl-dev install.

Summary
This PR adds a new GitHub Actions CI workflow that tests the codebase in a portable configuration without the Intel MKL library dependency. This provides a quick smoke test to ensure the project builds and tests successfully with only standard C++17 compiler support.
