Conan and Raspberry Pico, how to use together? - cmake

Question

Good morning!
I'm rewriting this question because, after a lot of reading and try-fails, I go further on that but I get staked again.
What I'm trying to accomplice here is: Use Conan as a Package manager for the embedded device "Raspberry PICO" from my Mac (with CLion)
The change from the previous question is that now I'm creating a package and I do not use only the "standalone" packages manager.
This "package" is on github.com. To install and try to compile it, you will need also the Pico SDK.
Some facts:
The new c++ project without Conan but with SDK is compiling and working on an embedded device.
The Conan project without Pico SDK is compiling correctly.
I really tried every possible configuration on the profile file and there are two mainly configuration profiles that brings to two different errors during build:
The first one is without any environments. This is because on CLion I'm not adding any environment and the project itself (without conan, but oblivious with SDK for pico) is builder correctly.

ps. The commented lines are additional tests that resolve on the same result after conan build ..
The error is this:

Also here I did all the variants and tests, but everything leads to this error. Besides, I checked the toolchain paths and there are correct.
I'm completely lost now. :(
