When working with large CMake projects, the configuration and generation phases can become slow. What systematic approaches (e.g., using CMake's --trace, --trace-expand, time commands, or external profiling tools) can be employed to measure where time is spent, and how can the results be interpreted to identify and mitigate bottlenecks?
CLion allows developers to decouple the IDE from the build environment using Remote Toolchains via SSH. This setup synchronizes source code to a remote host and executes CMake commands using the remote system's compiler and debugger. A discrepancy exists between the environment variables available in the remote shell and those recognized by the CLion CMake p
Managing Dependency Boundaries A project utilizing modern CMake (version 3.15+) aims to transition from global directory-based configurations to a strict target-based architecture. The goal is to ensure that usage requirements, such as include directories and compile definitions, are propagated only to the specific targets that link against a dependency. The
Goal Determine whether CMake's string(TIMESTAMP) can reliably produce a timezone name ( %Z ) when the underlying system lacks timezone data, and what the expected output should be in such cases. Constraints/Uncertainty The command forwards the format string to the C runtime's strftime , which may return an empty string for %Z if timezone information is unava
Goal Reduce network bandwidth and disk usage in CI pipelines by enabling shallow clones of external projects declared with FetchContent_Declare . The current default performs a full clone, which can be costly for large repositories. Unresolved Decision There is no documented option to set a default shallow clone depth for FetchContent . Developers must manua
Issue description CLion 2023.2 automatically triggers a CMake project reload whenever a CMakeLists.txt file is edited. When two or more such files are modified in quick succession, the IDE typically presents only one reload prompt, leaving the second file’s changes unprocessed. This behavior is documented under CMake project synchronization but remains unres
CLion 2023.2 introduced preliminary C++20 module support, but the feature is limited to the Clang compiler. When a CMake project targets GCC 11 or newer and includes a module interface unit, the IDE marks the file as an error, even though GCC compiles the module without issue. Additionally, the IDE’s module import completion is incomplete and it fails to pro
