qibuild.cmake - CMake tools

This module contains function to handle CMake managed project.

qibuild.cmake.get_known_cmake_generators()

Get the list of known cmake generators. Assume cmake is in PATH, or path to cmake is correctly configured in ~/.config/qi/qibuild.xml

qibuild.cmake.get_cached_var(build_dir, var, default=None)

Get a variable from cmake cache

Parameters:

• build_dir – CMakeCache.txt file directory
• var – Requested variable
• default – Default value if not found (default: None)

Returns:

the variable value

qibuild.cmake.cmake(source_dir, build_dir, cmake_args, env=None, clean_first=True, profiling=False, debug_trycompile=False, trace_cmake=False, summarize_options=False)

Call cmake with from a build dir for a source dir. cmake_args are added on the command line.

Parameters:

• env – defines the environment used when calling cmake os.environ will remain unchanged
• clean_first – Clean the cmake cache
• summarize_options – Whether to call display_options() at the end

For qibuild/CMake hackers:

Parameters:

• profiling – Profile CMake executions
• debug_trycompile – Call cmake with --debug-trycompile
• trace_cmake – Call cmake with --trace The results will be written in <build>/cmake.log

qibuild.cmake.display_options(build_dir)

Display the options by looking in the CMake cache

qibuild.cmake.read_cmake_cache(cache_path)

Read a CMakeCache.txt file, returning a dict name -> value

qibuild.cmake.get_cmake_qibuild_dir()

Get the path to cmake modules.

First, look for a project named qibuild in the worktree, (if a worktree was passed, then, assume we are using qibuild from sources, then assume we are using an installed version of qibuild.

qibuild.cmake.get_binutil(name, cmake_var=None, build_dir=None, env=None)

Get a tool from the binutils package. First, look for it in the CMake cache, else look for it in the system.

Note that after a call to CMAKE_FORCE_C_COMPILER() in a CMake toolchain file, CMAKE_AR, CMAKE_OBJDUMP et al. should be correctly set in cache.

qibuild.cmake.check_root_cmake_list(cmake_list_file)

Check that the root CMakeLists is correct.

• It should contain a cmake_minimum_required() line
• It should contain a call to project()
• If find_package(qibuild) is called, it should be called after project()
