Building sysutils/synergy on powerpc I see an error from cmake:
Target "core" requires the language dialect "CXX14", but CMake does not know the compiler flags to use to enable it.
with "core" replaced by all targets individually.
Could you please confirm that adding compiler:c++14-lang to USES resolves this for you?
I just confirmed, adding "compiler:c++14-lang" to the USES list lets it build correctly.

Thank you for confirming.
