When zlib is built via an add_subdirectory() call, ${CMAKE_SOURCE_DIR}
is the source directory of the parent project. Use
${CMAKE_CURRENT_SOURCE_DIR} instead to refer to the source directory of
the zlib project.
Remove a redundant include_directories(${CMAKE_CURRENT_SOURCE_DIR}) call
in the if(MSVC) block.
Note: This pull request is essentially the same as
madler#471. The only difference is to use
MAKE_CURRENT_SOURCE_DIR instead of PROJECT_SOURCE_DIR.

Move the include_directories() call with the source and binary directories of ext/zlib after add_subdirectory(ext/zlib) to work around a zlib/CMakeLists.txt bug fixed by madler/zlib#818. The parent project's include directories at the time of an add_subdirectory() call are used by the child project, so the order of include_directories() and add_subdirectory() is important.

I reproduced the bug with libavif v0.9.3 and zlib v1.2.11. I verified with libavif v0.9.3 and zlib commit ed16107 that the bug is gone. Thanks! |
