> FWIW, I have been experimenting with auto-generating CMake from my Bazel BUILD file for my project https://github.com/google/upb. My plan is to use Bazel for development but have the CMake build be a fully supported option also for users who don't want to touch Bazel. Thank you for your answer. I really wish the auto-generation of CMake build scripts will solve the problem(s). But even that I have doubts. The way Bazel works will make very hard to auto-generate "standard modern" CMake that allows external dependencies. This is orthogonal to the way Bazel works.

> Nix, Guix and Spack packager managers solved the C++ ABI issue a long time ago Yes this is certainly something that is solvable at the package manager level also. And this approach will certainly have shorter compile times. I agree it would be nice if Bazel integrated with package managers like this more easily. I hope Bazel adds support for this. There is a trade-off though: with less control over the specific version of your dependencies, there is a greater risk of build failure or bugs arising from an untested configuration. Basically this approach outsources some of the testing and bugfixing from the authors to the packagers. But it's a trade-off I know many people are willing to make. > Can I use that to specify a flag to some target and not some other ? Without having to build sequentially each of them ? You can put copts=["<

opt>"] in the cc_library() rules in the BUILD file. This will give per-target granularity. You can add a select() based on compilation_mode if you need to define opt-only flags: https://docs.bazel.build/versions/master/configurable-attrib... > Bazel try to build in isolated environment but do half of the job. It still depends on system compiler, and do not chroot nor "compiler-wrap" ( c.f Spack ) making the build still very vulnerable of system side effect and update. Bazel allows you to define your own toolchain. This can support cross-compiling and isolating the toolchain I believe, though I don't have any direct experience with this: https://docs.bazel.build/versions/master/toolchains.html > I can understand that Bazel is very convenient in Google environment with Google resources. But it's a nightmare for everyone I talked to outside of Google. I hear you and I hope that we see some improvements to integrate better with package managers. FWIW, I have been experimenting with auto-generating CMake from my Bazel BUILD file for my project https://github.com/google/upb. My plan is to use Bazel for development but have the CMake build be a fully supported option also for users who don't want to touch Bazel.
