This is a playground for demonstrating symbol visibility conflicts between libraries in cmake and ways to resolve them, e.g by using PUBLIC/PRIVATE visibility tags on links.
target_link_libraries (mylib yourlib)defaults to 'PUBLIC', which means any symbols in yourlib will be exposed in the export table
of mylib, and also all the compiler properties/flags/include paths/etc.
target_link_libraries (mylib PRIVATE yourlib)means that I will be a full consumer of yourlib still, but the linker will not expose its symbols upstream.
But can you still see their symbols?
Clone the repository and cmake-configure:
cmake -G Ninja -B build -S .
# ^- source from this directory (where CMakeLists.txt is),
# ^- use './build' as the cmake cache/build directory,
# ^- optionally specify the project generator to useAttempt to build:
cmake --build build # assuming you used '-B build',
# cmake --build output # if you used '-B output' instead, e.g
