CMake 3.24 has support for dependency providers

• cmake-init-fetchcontent

  4 2 1.8 CMake

  Example for optionally vendoring using FetchContent

You can see that in action here: https://github.com/friendlyanon/cmake-init-fetchcontent This example has the idiomatic find_package(headeronly REQUIRED) call in the CMakeLists.txt, but when configuring ${sourceDir}/cmake/find is added to CMAKE_MODULE_PATH, so the FetchContent code is run to "find" the dependency. There are comments to further explain this.

• cmake-init

  164 1,805 8.1 CMake

  The missing CMake project initializer

The book is nice to have but absolutely not necessary. cmake-init was created without the book and someone who has said book told me that it basically implements everything that the book recommends you do and some more.

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• Vcpkg

  146 21,377 10.0 CMake

  C++ Library Manager for Windows, Linux, and MacOS

  

Not if they if(COMMAND) correctly and use cmake_language(CALL) as described. Basically both need to implement what is done here: https://github.com/microsoft/vcpkg/pull/23195
