CPM.cmake/README.md

CPM

CPM is a very simple package manager written in Cmake based on the amazing DownloadProject script. It is extremely easy to use and drastically simplifies the inclusion of other Cmake-based projects from github.

Usage

To add a new dependency to your project simply add the Projects target name, the git URL and the version. If the git tag for this version does not match the pattern v$VERSION, then the exact branch or tag can be specified with the GIT_TAG argument.

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)

project(MyParser)

# add dependencies
include(${CMAKE_CURRENT_SOURCE_DIR}/cmake/CPM.cmake)

CPMAddPackage(
  NAME LarsParser
  GIT_REPOSITORY https://github.com/TheLartians/Parser.git
  VERSION 1.2
  GIT_TAG master # optional
)

# add executable
set (CMAKE_CXX_STANDARD 17)
add_executable(my-parser my-parser.cpp)
target_link_libraries(cpm-test LarsParser)

Current Limitations

• First version used: in diamond dependency graphs (e.g. A depends on C(v1.1) and A depends on B depends on C(v1.2)) the first added dependency will be used (in this case C@1.1).
