This recipe demonstrates how to set the visibility of symbols for a shared library. The best practice is to keep all symbols hidden by default, explicitly exposing only those symbols that we want to be used by dependents on our library. This is achieved in two steps. First of all, we need to instruct the compiler to hide symbols. Of course, different compilers will have different options available, and directly setting these by hand in our CMakeLists.txt would not be cross-platform. CMake offers a robust and cross-platform way of setting symbol visibility by setting two properties on the shared library target:
- CXX_VISIBILITY_PRESET hidden: This will hide all symbols, unless explicitly marked otherwise. When using the GNU compiler, ...
