[question] How to replace conanbuildinfo.cmake

[diogomatos3]

What is your question?

Hello community,

In my project, we still generate conanbuildinfo.cmake and run conan_basic_setup().
We would like to migrate and use CMakeToolchain and CMakeDeps instead.

But unfortunately, we get now several "No such file or directory" errors. So the path to the header files seems to be unknown. Something that conan_basic_setup() macro was covering.

How to proceed?

I am basically following https://docs.conan.io/en/1.64/reference/conanfile/tools/cmake/cmake.html#cmake

Thanks in advance.

Have you read the CONTRIBUTING guide?

Hi @diogomatos3

The important bit is the "generators". In your linked doc page, you can see:

from conan.tools.cmake import CMake, CMakeToolchain, CMakeDeps

 def generate(self):
        tc = CMakeToolchain(self)
        tc.generate()
        deps = CMakeDeps(self)
        deps.generate()

Because the recipe is using the new CMakeToolchain and CMakeDeps generators.
These generators are fully transparent, meaning that nothing should be added to the CMakeLists.txt, so the include(conanbuildinf.cmake) and other related code must be removed.

When you remove them, things should work.
You can see a full working example with the conan new hello/0.1 -m=cmake_lib template, that you can execute in an empty folder, then do conan create .
