waylandpp-dev cmake configuration includes build time path

Package Information

• Package name: waylandpp-dev
• Package version: 1.0.0-r1
• Alpine version: 3.19
• Alpine architecture: x86_64

Summary

the cmake configuration cant be used, have to workaround via PkgConfig to use library.

i would suspect that the issue is present in 3.20/edge too since the packaged version is the same.

add this to the backlog or don't fix, really does not matter to me, i just added the issue since it popped up so it can be fixed.

Steps to reproduce

CMakeLists.txt

project(wlpp-testing)
add_executable(${PROJECT_NAME} main.cxx) # main.cxx is just a empty file to trigger the cmake error
find_package(waylandpp REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE Waylandpp::wayland-client++ )

output occured:

  CMake Error in testing/CMakeLists.txt:
  Imported target "Waylandpp::wayland-client++" includes non-existent path

    "/home/buildozer/aports/community/waylandpp/src/waylandpp-1.0.0/"

  in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:

  * The path was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and references files it does not
  provide.
