Пакет QtAV msys2: cmake говорит, что libQtAV.dll.a "файл не существует", но он существует

0 голосов
/ 08 ноября 2018

Я пытаюсь установить QtAV и связать его с моим проектом на MSYS2. Я успешно установил пакет для QtAV в мою среду msys2. Однако, когда я добавляю find_package (QtAV) в мой CMakeLists.txt, он выдает ошибку об одном из несуществующих статических файлов ссылок. Но когда я смотрю, он наверняка существует!

Что мне не хватает, что это не работает?

Ошибка: 

$ mingw32-make.exe
-- Boost version: 1.68.0
-- Found the following Boost libraries:
--   system
--   log
--   date_time
--   log_setup
--   filesystem
--   thread
--   regex
--   chrono

CMake Error at C:/msys32/mingw32/lib/cmake/QtAV/QtAV-config.cmake:68 (message):
  The imported target "QtAV" references the file

     "/mingw32/lib/libQtAV.dll.a"

  but this file does not exist.  Possible reasons include:

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

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "C:/msys32/mingw32/lib/cmake/QtAV/QtAV-config.cmake"

  but not all the files it references.

Но вы можете видеть, что файл существует:
