You will find here a CMake module allowing to easily create a build system on top of ExternalProject module.

• Intuitive and easy way to "pass" CMake variables to external project. By default, variables are associated with CMAKE_CACHE_ARGS.
• Support association of CMake variable with labels.
• Automatically associate variables with CMAKE_ARGS if a multi-configuration CMake generator is used and ${CMAKE_CFG_INTDIR} is found in the value.
• Automatically set external options LIST_SEPARATOR, CMAKE_GENERATOR, CMAKE_GENERATOR_PLATFORM and CMAKE_GENERATOR_TOOLSET.
• If CMake >= 3.24, set DOWNLOAD_EXTRACT_TIMESTAMP to 1. See CMP0135
• If not explicitly enabled, ensure User Package Registry look up using find_* commands is disabled.
  • If CMake >= 3.16, set CMAKE_FIND_USE_PACKAGE_REGISTRY to OFF otherwise set CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY to ON.
• Display a well-formatted and user friendly summary of the included external projects. For example, see here
• Support Ninja generator:
  • If supported, USES_TERMINAL_* options are always set to dependent projects.
  • The following variables are automatically propagated to all projects:
    • CMAKE_EXPORT_COMPILE_COMMANDS
    • CMAKE_JOB_POOL_COMPILE
    • CMAKE_JOB_POOL_LINK
    • CMAKE_JOB_POOLS
• Intuitive handling of USE_SYSTEM options.
• Recipe to write external project file that can be:
  • downloaded/configured/built/installed
  • and/or found on system using find_package(<projectname> ...) calls
  • and/or explicitly specified using -D<projectname>_DIR:PATH=... variables.

Two possible approaches:

• Use git submodule to reference this repository.
• Copy ExternalProjectDependency.cmake into your source tree making sure you reference the SHA in the associated commit message.
