Specify library name and version: cmake/all

I will push the patch upstream but want to test it first on CI.

This will fail

The offending CMake is NOT the one we are building but rather the one we are using to build it (we build CMake with CMake)

Hence, you would need to patch the installed CMake on the Windows CI machines

The sources contain:

# Make sure we can find internal find_package modules only used for
# building CMake and not for shipping externally
list(INSERT CMAKE_MODULE_PATH 0 ${CMake_SOURCE_DIR}/Source/Modules)

So there is hope 🤞

@Croydon
The patch is working!
The MSVC logs still contain the MSB warning so c3i's props file was not patched yet.

Wohoo. Nevermind, don't listen to me. You are doing amazing work 🎉 🥳 🎉

So, we are going to merge this and push it upstream? 🤔

just out of interest, what is the actually problem solved here ?
is this patching cmake to satisfy conan hooks?

Croydon commented Oct 7, 2020

No, there was a change in the Windows CI which causes MSVC to produce a warning which is treated by CMake effectively as an error

looks good, not sure if an approval from me helps to merge that faster, but for the case it helps, here it is :-)

We will fix it in the infra, no need to make the recipe more complex just because we are not doing things right in the backend.

@danimtb , what about releasing a new version of C3i? I think it is ready.

@jgsogo Upstream already agreed to welcome a PR fixing this, so I don't see a reason why we shouldn't patch existing versions on CCI.

The patch is rather small and can be dropped for future versions as soon as it is upstreamed

I prefer not to add complexity (maintenance, ifs,...) to the recipe if it is not needed. This is a PR we'd never have done if the CI hadn't failed. After #3138 this is no longer a problem.

Thank you for pushing this forward @madebr

It is an upstream problem and may also affect other environments similar to C3I, but since it is now upstreamed, it at least won't be a problem for future CMake versions. So I guess it is fine with me if we don't patch the older versions.

That said, we got a new "unexpected error" here: 🙈

I'll close it. I see the other pr will apply the openssl version bump.
