To add or update variables in the project settings: Only project members with theĬan add or update project CI/CD variables. You can add CI/CD variables to a project’s settings. Job : variables : FLAGS : ' -al' LS_CMD : ' ls "$FLAGS" $$TMP_DIR' script : - ' eval "$LS_CMD"' # Executes 'ls -al $TMP_DIR' Add a CI/CD variable to a project If it’s defined in a job, only that job can use it. If the variable is at the top level, it’s globally available and all jobs can use it. You can use the variables keyword in a job or at the top level of the. gitlab-ci.yml file,ĭefine the variable and value with variables keyword. If you run a merge request pipeline in the parent project for a merge request from a fork,Īll variables become available to the pipeline. Make sure each variable is defined for the scope you want to use it in.īy default, pipelines from forked projects can’t access CI/CD variables in the parent project. Each shell has its own set of reserved variable names. Variable names are limited by the shell the runner uses There are two types of variables: File or Variable.

Or have them prefilled in manual pipelines. You can override variable values manually for a specific pipeline,

For all projects in a GitLab instance in the instance’s settings.

For all projects in a group in the group’s setting.

The script outputs the stage for the test_variable, which is test: Test_variable : stage : test script : - echo "$CI_JOB_STAGE"

You can use predefined CI/CD variables or define custom:

You can see this question how to set multiple compile definitions for target executable for more information also from this.

Target_compile_definitions(trie_io_test PRIVATE UNIT_TESTING=1 IO_TEST=1) If you want to add compile definition for target, you can use this function target_compile_definitions which is more convenient， like add multiple compile definitions once, like: add_executable (trie_io_test demo12.cpp) Use COMPILE_DEFINITIONS for fine tuning of target or specific Use add_definitions when you want add to compiler command lineįor sources in the current directory and below. And, since those projects use it, any newer projects that are based on what people learn from reading those CMakeLists files are also quite likely to use add_definitions.īut if using COMPILE_DEFINITIONS alone is sufficient for your needs, there's certainly nothing wrong with that.

So: add_definitions is primarily useful to configure pre-existing CMakeLists files - for those projects that have been around since before COMPILE_DEFINITIONS was introduced. And sometimes doing essentially the same thing in multiple differing ways. sometimes to the detriment of clarity and simplicity.

The CMake devs work very hard to maintain backwards compatibility. They will always both be around: since 99%+ of the existing CMakeLists.txt files in the world use add_definitions, it simply would not be wise to remove it. Add_definitions has existed in CMake since the very first build of CMake came online more than a decade ago.ĬOMPILE_DEFINITIONS is simply the newer, more flexible and fine-grained way to do it.
