[conan|cmake] Migrate to Conan 2.0

[IceflowRE]

How i hate these settings.yml check. This is such a design failure.

[IAmNotHanni]

I can't really follow what you are doing there. I don't have enough conan and CMake knowledge. I can test though.

[IceflowRE]

Haha right some explanation:

This will make that we do not have to use conan to get dependencies. For example if someone has it installed and do not want to use conan this allows him to do so. We just tell conan to give us FindXXX cmake files which do we use. Which configures everything.

This also prepares us for Conan 2.0. Who is planned to be less intrusive in CMake.

Of course for CI and bug reports we have to insist on conan due to reproducable builds.

On Ubuntu the output folder is example and not bin anymore?

[IAmNotHanni]

Hmm, no it shouldn't be example, it should be bin?

This is working fine on m Linux Mint using cmake 3.22.4, conan 1.53.0, and clang++14.

Ok let's start with this:

Still works with updated dependencies after you pushed Iceflower :)

Could you try it on windows but delete rename with appending an underscore beforehand

• C:\.conan
• C:\Users\<username>\.conan\data

I removed this code part because it's not necessary to have it anymore:

find_program(GLSL_VALIDATOR glslangValidator REQUIRED)
if(NOT GLSL_VALIDATOR)
    message(FATAL_ERROR "glslangValidator not found!")
endif()

I get the following errors now:

We have glslang/1.3.236.0 in our conanfile.py. The question is now: how to use it for compiling the shaders?
