Subject: [PATCH] Add libmagic.pc
|
||
|
|
|
||
|
|
libmagic can optionally depends on xz (for lzma) or bzip2 since version
|
||
|
|
5.38 and
|
||
|
|
https://github.com/file/file/commit/b259a07ea95827f565faa20f0316e5b2704064f7
|
||
|
|
so add libmagic.pc so package (such as gerbera) that links with libmagic
|
||
|
|
will be able to use pkg-config to retrieve those static dependencies
|
||
|
|
For example, this will avoid the following build failure:
|
||
|
|
|
||
|
|
[100%] Linking CXX executable gerbera
