This project is an example project generated with cmake-init with the purpose of showing off how to create an internal dependency as an implementation detail in the form of a static library.
See the BUILDING document.
Right now, CMake does not combine the .a or .lib files, which means that if
your public static library target depends on one as an internal dependency, you
must also install the internal dependency, which will show up in the install
interface as a $<LINK_ONLY:...> generator expression. The purpose of this
genex is that the public static library target does not contain the object code
form the internal static library dependency, so it must also be linked into a
consuming final target. If CMake didn't do this for you, then you would end up
with linker errors due to missing symbols related to an implementation detail.
This list will assume that your public target is static or shared depending on
the value of CMake provided BUILD_SHARED_LIBS. Changes to be made:
- Make the config file configurable.
- Setup a new export set for the internal dependency.
