Staging targets

This module make libraries and executables build in this projects available to others projects.

qi_stage_lib(target [DEPRECATED <deprecated> ...]
    [DEPENDS <depends> ...]
    [INCLUDE_DIRS <include_dirs> ...]
    [PATH_SUFFIXES <path_suffixes> ...]
)
Arguments:
  • target – a target created with qi_create_lib
  • DEPRECATED – specify a deprecated message. This message will be displayed each time another project use that lib.
  • DEPENDS – if not given, ${TARGET}_DEPENDS will be guessed from the previous calls to qi_use_lib(). Use this (whith care!) to override this behavior. One should list all the (public) “direct” dependencies and their (public) dependencies.
  • INCLUDE_DIRS – if not given, ${TARGET}_INCLUDE_DIRS will be guessed from the previous calls to include_directories() Use this (whith care!) to override this behavior.
  • PATH_SUFFIXES – when your header is installed in foo/bar.h, but you still need to do #include <bar.h>, you can set PATH_SUFFIXES to ‘foo’. Be careful to test the intall rules of your headers if you choose to do so.

Generate a ‘name’-config.cmake, allowing other project to find the library. Usage of the various arguments are a bit tricky, so please read Using qi_stage_lib before using them

qi_stage_header_only_lib(name [DEPRECATED <deprecated> ...]
    [DEPENDS <depends> ...]
    [INCLUDE_DIRS <include_dirs> ...]
    [PATH_SUFFIXES <path_suffixes> ...]
)
Arguments:
  • name – the name of the library, clients of the library can use qi_use_lib(... NAME)
  • DEPRECATED – specify a deprecated message. This message will be displayed each time another project use that lib.
  • DEPENDS – if not given, ${NAME}_DEPENDS will be empty the previous calls to qi_use_lib().
  • INCLUDE_DIRS – if not given, ${NAME}_INCLUDE_DIRS will be guessed from the previous calls to include_directories() Use this (whith care!) to override this behavior.
  • PATH_SUFFIXES – when your header is installed in foo/bar.h, but you still need to do #include <bar.h>, you can set PATH_SUFFIXES to ‘foo’. Be careful to test the intall rules of your headers if you choose to do so.

Generate a ‘name’-config.cmake, allowing other projects to find the header-only library. If the library has some dependencies, use something like:

find_package(FOO)
include_directories(${FOO_INCLUDE_DIRS})
qi_stage_header_only_lib(bar DEPENDS FOO)

qi_stage_bin(target)
Arguments:
  • target – the name of a target

Generate a ‘name’-config.cmake, allowing other projects to find the binary

Example

# in foo/CMakeLists.txt
qi_create_bin(foo foo.cpp)
qi_stage_bin(foo)

# in bar/CMakeLists.txt:
find_package(foo)
# Do something with ${FOO_EXECUTABLE}

qi_stage_cmake(module)
Arguments:
  • module – path to the module file, relative to CMAKE_CURRENT_SOURCE_DIR

stage a cmake file For instance, assuming you have a foo-config.cmake file containing my_awesome_function, you can do:

qi_stage_cmake("foo-config.cmake")

Then later, (in an other project, or in the same project):

find_package(foo)
my_awesome_function()

qi_stage_script(file_name [TRAMPOLINE]
    [PYTHON]
    [DEPENDS <depends> ...]
)
Arguments:
  • file_name – Path to the script in source dir.
  • TRAMPOLINE – If set, will generate a trampoline script in sdk binary dir. Use this flag if your script uses any element that is built.
  • PYTHON – set if script is written in python
  • DEPENDS – list of target or packages this script depends on. Used for trampoline script generation only.

Stage an executable script

Will stage a cmake file so that others can locate the script. Use like this:

qi_stage_script(src/myscript)

And in other projects:

find_package(myscript)
use_script_in_function(${MYSCRIPT_EXECUTABLE})

qi_use_lib(name [<remaining args> ...]
    [ASSUME_SYSTEM_INCLUDE]
)
Arguments:
  • name – The target to add dependencies to.
  • args (remaining) – dependencies
  • ASSUME_SYSTEM_INCLUDE – Use -isystem for including dependencies. Useful for instance to ignore warnings coming from 3rd party headers.

Handles dependencies between projects.

Call find_package for you, then do all the include_directories and target_link_libraries that are needed.

Note

The name must be an existing target, so you must call qi_use_lib after qi_create_bin or qi_create_lib

You can however call qi_use_lib several times, for instance:

qi_create_bin(foo)

# ...

qi_use_lib(foo bar)
if(UNIX)
   qi_use_lib(foo PTHREAD)
endif()

qi_stage_dir(directory)
Arguments:
  • directory –

    (optional): the directory to register, relative to CMAKE_CURRENT_SOURCE_DIR. Defaults to CMAKE_CURRENT_SOURCE_DIR

    Make sure configuration and data files in the given directory can be found by qi::findData() in this project or any dependency

For this to work, configuration files should be in etc and data files in share

Note that this function does not create any install rule
