Hi,
I have a project using CMake 3.9.
The project contains a header only library mylib.
The library hast set the following property:
target_compile_features(mylib INTERFACE cxx_std_17)
Now I try to add otherlib to mylib (INTERFACE as well). otherlib has set
some c++11 compile_features.
When I try to compile tests for my lib I see gnu++11 as requested
standard. Without otherlib gnu++17 is selected.
Could this be a bug or I am using CMake in a wrong way. What is the best
way to set the required standard for a header-only library?
Thank You
Jan
