Nuget will use it to install/restore dependencies, if they are missing. cmake propagate dependencies using find_package. The download step happens at project build-time. As we know gtest is github-hosted and cmake-based project. cmake file in the way I described above is if the project I’m building isn’t in a top level folder for some reason (such as when it’s in an “examples” subfolder of another project), then the relative paths will be wrong. txt with the following contents: CMake has accurate dependencies and allows for minimal rebuilds of only the code that has changed. 1: Alexandru Croitor (2): AutoGen: Fix over-specified direct dependencies of custom command; AutoGen: Add test to check for correct AutoMoc dependencies So the first problem I’ve run into using a Common/Settings. Seeing how various topics all work together in an example project can be very helpful. So one solution should be to use fixup_bundle, like here suggested, so hopefully he copy all DLLs, which he can detect with a dependency walker and are on path. FetchContent has a little sense for non-CMake projects: FetchContent_MakeAvailable uses add_subdirectory which expects the project to have CMakeLists. 1 since 3. CMake offers two modules to satisfy missing dependencies on-the-fly: the ExternalProject and FetchContent modules. 13.

You'll install dependencies, configure, I am trying to use CMake to set up some simple dependencies between a C++ project and the libraries that it uses. A cleaner approach would be to place the download in a directory in the binary dir and compile from there. I want to use git submodules for this, because. This is kind of documented here, but basically for every find_package() call you're supposed to add a corresponding find_dependency() call into your configuration file. The previous behavior will be restored in 3. Introduction . My minimal (not) working example would be: CMakeLists. It will do the download during CMake configure, Note that switching to ExternalProject means you won’t have access to anything from your dependency (fmt in this case) during CMake’s configure step, so you won’t have things like the fmt::fmt library defined for you. Whereas ExternalProject_Add() downloads at build time, the Learn how to download your dependencies at configure-time with FetchContent. – Patrick Fromberg. CMake offers two modules to First, we have to download CPM’s script on our project and include it on CMake. With this you don't need to know the dependencies between the supporting libraries and - with the CMake level "includes" - you will only end-up with the targets you really CMake » 3. lib/. 3 CMake FetchContent does not Ninja is used to build Google Chrome, parts of Android, LLVM, and can be used in many other projects due to CMake's Ninja backend. Let's say I have three projects, each one in a different repository: Core: library exporting a lot of useful stuff. cmake --graphviz=test. But currently I have no idea how is best way to use it on a target, following code won't work, When you use ExternalProject, you need to set up a lot of boilerplate to make the external project use the same settings as the "parent" project, such as the toolchain file, c++ compiler, c++ standard, configuration types / build type, etc. There are two ways to do this. 8. pc file can contain incomplete list of third-party dependencies and may not work in some configurations, especially for static builds. IMO much much better to use that than git submodule, since: . And in my case find_package(PkgConfig) did not help. g. I have a CMake project with two submodules A and B. Rose. As it says in the documentation,. Check what exact configuration you have built. If you’re a library writer, Object libraries cannot be chained this way.
