Correct is that we want to write

find_package(editorconfig "0.12.0)

i.e., with a version. This is missing in this find module, see the LibGit2 find module. Could you extend this?

It seems there isn’t any version string in library headers (editorconfig.h, editorconfig_handle.h), is there any other cross-distribution way to obtain library version?

editorconfig-core-lua doesn’t check C library version (CMakeLists.txt:49). Actually I’m not sure if setting oldest acceptable version in KTextEditor is really needed.

Hm, looking at libgit2 I have:

-rwxr-xr-x 1 root root 906728 Dez  2 12:13 libgit2.so.0.24.0
lrwxrwxrwx 1 root root     17 Jan  7 20:05 libgit2.so.24 -> libgit2.so.0.24.0

Looking at editorconfig, I have:

lrwxrwxrwx 1 root root    20 Feb 12 17:17 libeditorconfig.so -> libeditorconfig.so.0
lrwxrwxrwx 1 root root    25 Feb 12 17:17 libeditorconfig.so.0 -> libeditorconfig.so.0.12.1                                                                                                  
-rwxr-xr-x 1 root root 18320 Aug 17 12:42 libeditorconfig.so.0.12.1

So the shared library definitely has a version number. I cannot say anything with respect to binary compatibility guarantees of the editorconfig library, but in general, checking for a version is a good idea :-)

I think we need input from developers who know cmake and the extra-cmake-modules here.

FindLibGit2.cmake and other files include such fragment:

if(LIBGIT2_FOUND AND NOT TARGET LibGit2::LibGit2)
    add_library(LibGit2::LibGit2 UNKNOWN IMPORTED)
    set_target_properties(LibGit2::LibGit2 PROPERTIES
        IMPORTED_LOCATION "${LIBGIT2_LIBRARY}"
        INTERFACE_COMPILE_OPTIONS "${LIBGIT2_DEFINITIONS}"
        INTERFACE_INCLUDE_DIRECTORIES "${LIBGIT2_INCLUDE_DIR}"
    )
endif()

Is something similar needed in EditorConfig’s case?
