I tried to use Ninja locally on my Windows development box but cmake in that environment does complain that that installed cmake does not support Ninja as a build tool. I'm just curious which version or flavor of cmake could generate rules for Ninja? |
I used used CMake from MSVC 2022's C++ CMake tools for Windows, which identifies itself as
That's fair, I would say it reduces total time for the Windows builds even if configuration time may be longer, an example: with (n.b. with openssl cache miss, with a hit it would be even less) vs without these changes. These are just two examples but they align well with my measurements. That said, I understand that you may not necessarily wish to change NMake to Ninja in CI and will of course drop that commit if you wish. |
Got it. It's reasonable. Migrating from NMake to Ninja could be a future task. So, could you drop that commit and focus on the GHA caching and tweaking options for MSVC? Those of commit are still quite useful for us. And the dropped commit should be sent as another PR if you have a more cycles. |
Use CMAKE_SHARED_LINKER_FLAGS for MSVC to trigger creation of PDBs for dynamic libraries (i.e. fluent-bit.dll) instead of specifying target_link_options as those are inherited by the out_lib and hello_world examples causing intermittent build failures when attempting to overwrite fluent-bit.dll.pdb. Set the suffix of the import lib for fluent-bit.exe to .exe.lib so that it does not conflict with the static library's import lib. Signed-off-by: Erik Cederberg <erik.cederberg@sectra.com>
Enabling /DEBUG implicitly disables /OPT:REF and /OPT:ICF which leads to larger binaries (~25 % for x64 builds). Re-enable /OPT:REF for all builds and /OPT:ICF for 64-bit builds. Signed-off-by: Erik Cederberg <erik.cederberg@sectra.com>
Change caching to cache installed packages and run vcpkg upgrade to match the previous behavior where packages were re-built each time. Signed-off-by: Erik Cederberg <erik.cederberg@sectra.com>

Looks ok to me but waiting on @cosmo0920 to confirm - plus need it to be green in CI too before merge. |

I confirmed that this change won't affect to generate PDB for debugging purpose especially for WinDbg.
It looks great to me. 👍

fluent-bit.exe, and modify how debug data output is configured forfluent-bit.dllso that build outputs are not overwritten by other build outputs./DEBUGto match Microsoft's recommendations.All in all this reduces MSVC CI build times with ~20-25% if there is a cache hit for the vcpkg packages and the size of
fluent-bit.exeis reduced with about 20 %.Enter
