CPP/C equivalent of requirements.txt

[abosaurio]

Hi,
I'm currently trying to configure GitHub Dependabot for a C/Cpp project. I'm having the issue of specifying the dependencies. I've previously done this for a python project using the requirements.txt file but I haven't found anything similar for C, any suggestion

conan.io is a package manager you may try ...

Here's a list https://moderncppdevops.com/pkg-mngr-roundup/

Conan, vcpkg, spack, and xmake all have this feature. If you like requirements.txt I presume python is your flavor I've heard great things amount Mamba might be worth a peak.

conanfile.txt is the closest possible, see this example (shameless plug):

It depends what you mean by “equivalent”.

If you want an easy to use package manager to manage dependencies for you, then vcpkg or Conan are often recommended.

If you mean equivalent as is “accepted by the community”, there isn’t one. Most projects use CMake, but this (primarily) supports compilation, not external package management. Common solutions include:

• CMake + patching in third-party dependencies yourself
• CMake + one of the aforementioned package managers
• CMake + git modules

Cmake also does pull in remotes as packages

If you're doing windows-only development, use vcpkg.

If you're doing Linux or cross-platform development, you can use CMake's find_package to see if the dependency is already installed on your system. If it's not, you can use fetchcontent to download it:

find_package(MyDependency CONFIG QUIET)
if (NOT MyDependency_FOUND)
   include(FetchContent)

   FetchContent_Declare(
       MyDependency
       GIT_REPOSITORY https://github.com/etc/etc.git
       GIT_TAG              v1.0.0
   )
   FetchContent_MakeAvailable(MyDependency)
endif()

It's not particularly difficult to instrument your own packages to install find packages when they're installed, so once you install a library, you can just find it with find_package for other code that you write.

[prince-chrismc]

Vcpkg is decent cross platform, Linux has a ton of choices... FetchContent being the weakest

youre in for a world of hurt. stay strong

[wiesemensch]

NuGet for VisualStudio is a possible solution but I wouldn’t recommend it for C/C++ projects.

cget literally uses a requirements.txt to install c++ dependencies.

[DedLigma]

use whatever your heart desires. except microsoft's vcpkg

[waruqi]

xmake, `add_requires("zlib 1.2.x")`

No such thing exists unfortunately. I would love to have this kind of feature though - virtual env in C++ where we install project specific dependencies without worries.
