Could NOT find LIBZIP (missing: _libzip_pkgcfg)

libzip-1.7.3 provides its own cmake files that should be used. I solved this with this patch:

Hi @yurivict

Thanks for the report. Could you please tell if it is the commenting of the install section that did the trick or the find_package related change ? Does it work if you use find_package(libzip MODULE REQUIRED) ? Looks like a case issue :thinking:

[yurivict]

find_package(libzip MODULE REQUIRED) looks for Findlibzip.cmake and fails.

Both parts are needed.

But then, how can find_package(libzip REQUIRED) work ? It should also look for Findlibzip.cmake :thinking: I guess the install fails for the same reason, because of the path to the cmake...

But then, how can find_package(libzip REQUIRED) work ? It should also look for Findlibzip.cmake

No, it looks for standard cmake files that are installed by libzip and finds them,

Findzip.cmake is only needed when the project doesn't provide cmake files.

I found the same question, but I use a manually way: #find_package(LIBZIP MODULE REQUIRED) include_directories("C:/Program Files/libzip/include") link_directories("C:/Program Files/libzip/lib")\n and #target_link_libraries(libzippp PRIVATE libzip::zip) target_link_libraries(libzippp PRIVATE zip), it works.

Since I could not reproduce the issue, I'm closing it. Please, submit a PR if possible. Thanks.
