[question] Extend CMAKE_MODULE_PATH/CMAKE_PREFIX_PATH at consumers

[aagor]

What is your question?

Hi,

I want to package some CMake build scripts in a conan package.
For include(some-build-script.cmake) to work at consumers of this package, they must add the path of the CMake scripts to its CMAKE_PREFIX_PATH / CMAKE_MODULE_PATH.

I have not seen a way to conveniently add something like this.
The attributes that can be set inside package_info() don't cover this case.

Have I missed something?
What's the best solution for this problem?

Have you read the CONTRIBUTING guide?

Hi @aagor

I think you are interested in https://docs.conan.io/2/examples/graph/requires/consume_cmake_macro.html

Basically you need to self.cpp_info.builddirs = ["path/with/cmake"] so this path is added to the CMAKE_ paths (via conan_toolchain.cmake from CMakeToolchain

Hi @memsharded,

thanks, that is exactly what I asked for. I must have missed that.

May I suggest to extend the documentation of find_paths inside the CMakeToolchain documentation, to make that more easily discoverable when searching the documentation for CMAKE_XXXX_PATH (and maybe link the example somewhere)? Adding something like "Also adds the declared builddirs from cpp_info of host dependencies".

Yes, sounds good, this is pending some more detailed documentation, but it will probably be associated to the new CMakeConfigDeps generator, as this is information more associated to dependencies than to the toolchain.

Moving the ticket to the docs repo.
