The failure is the same on both Default and Unstable branches, and the YARP yarp-3.4 and Wearables master branches did add any new commit in the past two days, so the problem is due to some change in th environment.

[traversaro]

The reason why this is failing only on Wearables seems to be https://github.com/robotology/wearables/blob/6071817be71af3b55d3fdfd4f4f979c693589eff/CMakeLists.txt#L45 .

[traversaro]

Inspecting the logs, the following two packages changed:
CMake 3.19.7 --> 3.20.1
glew 3.3.3 ---> 3.3.4

So probably it is a CMake-related regression.

[traversaro]

I quickly tried locally by compiling wearables in the following two environments:

conda create -n wearables-working -c conda-forge -c robotology cmake=3.19.7 compilers yarp idyntree ninja

and

conda create -n wearables-not-working -c conda-forge -c robotology cmake=3.20.1 compilers yarp idyntree ninja

but it seems to be compiling fine in both cases, so the issue is more tricky or at least more related to CI/superbuild. Probably it is easier to run some test son CI directly.

[traversaro]

The diff in the linking command (left CMake 3.19.7 working, right CMake 3.20 not working):

It seems that ${LINKER_BIN} STREQUAL "ld" was not true with CMake 3.19.7, not sure why. However, the bug is that if the if is selected, the new options should be appended to CMAKE_SHARED_LINKER_FLAGS, not overwritten as this make the project ignore the value of the LDFLAGS environment variable, a problem similar to the one described in gazebosim/gazebo-classic#2922 .

[traversaro]

This should be fixed by robotology/wearables#110 .
