When comparing Bazel vs CMake, the Slant community recommends CMake for most people. In the question“What are the best open-source build systems for C/C++?” CMake is ranked 2nd while Bazel is ranked 8th. The most important reason people chose CMake is:
This way everyone can use their favorite IDE in order to develop CMake, Code Blocks, qtcreator, Visual Studio, (and more).
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Correct and repeatable builds
Builds only use input files that are explicitly declared in the build specification. On Linux, Bazel runs tools in a sandboxed environment that contain only the minimum necessary files required.
Pro Fast even at scale
Even at large scale it's pretty fast (it's based on what Google uses internally for their huge code base).
Pro Can rule shell commands
Pro Handles mixed language builds
Pro High level build descriptions
Pro Build rule errors are informative
When builds fail because of an issue in the build rules, the errors provided are usually very informative and helpful to resolve the issue.
Pro Good IDE support
Pro Standard protocol for remote execution and caching
Pro Remote execution of commands
Pro Compatible with different IDE's
This way everyone can use their favorite IDE in order to develop CMake, Code Blocks, qtcreator, Visual Studio, (and more).
Pro Built-in, cross-platform dependency finding
Pro Out-of-the-box GUI available
CMake comes with the fantastic ncurses GUI ccmake
out of the box. Large codebases including WeeChat use it, to the point that the developer never needs to touch CMake code, but it is highly readable if he wishes to examine it.
Cons
Con Draconian sandboxing, explicit inputs requirement
Requirement to explicitly name all inputs disqualifies Bazel for many workflows, e.g. those relying on tools that scan a directory tree themselves looking for files to process. Sandboxing as implemented in Bazel imposes further restrictions. If a command is successful when you type it in the shell, it should also be successful when pasted verbatim into a rule, but with Bazel it very often isn't.
Con Confusing for beginners
With so many capabilities, trying to implement with a simple project is overkill and unpleasant.
