MO2 CMake Common

This repository contains CMake macro and functions that are used in most MO2 repository to build uibase, modorganizer itself and plugins (C++/Python).

Getting Started

To get started, simply include the mo2.cmake file in your project:

# this can safely be included multiple time
include(path_to_cmake_common/mo2.cmake)

This will set some (not too intrusive) variables and define many useful functions, all prefixed with mo2_.

The basic MO2 plugin/executable CMake will then look like this:

# this is for a C++ plugin
add_library(my_plugin SHARED)

# configure the plugin - this will also set the sources of the plugin
# based on the file in the current directory (and subdirectory)
mo2_configure_plugin(my_plugin)

# install the target to MO2 installation path, typically in the
# plugins/ folder
mo2_install_target(my_plugin)

Configuring

The main entry-points are the the configure functions:

• C++
  • mo2_configure_target - this is the "base" configuration, which should not be used most of the time (this one is called by other functions),
  • mo2_configure_uibase - specific for uibase, should not be used elsewhere,
  • mo2_configure_plugin - configuration for a C++ plugin,
  • mo2_configure_library - configuration for static or shared libraries,
  • mo2_configure_executable - configuration for executables, including the main MO2 executable,
  • mo2_configure_tests - configuration for tests.
• Python
  • mo2_configure_python.

The function are documented so you can look at the documentation to see what arguments are available.

Dependencies

You can add dependencies to the target by using the standard target_link_libraries, but this might be difficult when looking for MO2 dependencies, such as other libraries or Qt.

The mo2_configure_XXX accept PRIVATE_DEPENDS and PUBLIC_DEPENDS parameters that can be used to add dependencies to the target in an easier way. These parameters accept 3 types of dependencies:

• Qt dependencies, that should be specified as Qt::COMPONENTS, e.g., Qt::Core or Qt::Widgets. Note that the Qt:: is version-independent, MO2 will add the proper version for you.
• Boost dependencies - For header only libraries, you can simply pass boost, for non-header only libraries, you can pass boost::COMPONENT, e.g., boost::threads.
• MO2 dependencies - Those are either components available via the MO2 build system, such as zlib or libbsarch, or other MO2 components such as game_gamebryo.

Installing

For C++ plugin, you need to call mo2_install_target to install the plugins or executable in MO2 installation directory. Where the target should be installed is defined in the mo2_configure_XXX function (which should be called before mo2_install_target).

Installing Python plugins does not require extra call apart from mo2_configure_python.

Examples

All MO2 repositories use these functions, so you can look at any repository to get details on how to use them. Here are entry points for the various type of plugins:

• game_skyrimse for a plugin that depends on a static library built by MO2.
• game_gamebryo for a static library example.
• installer_wizard for a Python plugin (module).
• fnistool for a Python plugin (simple file).
