The imported target "Qt5::Core" references the file

CMake Error at /usr/local/lib/cmake/Qt5Core/Qt5CoreConfig.cmake:15 (message):
  The imported target "Qt5::Core" references the file

     "/usr/local/.//mkspecs/macx-clang"

  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

     "/usr/local/lib/cmake/Qt5Core/Qt5CoreConfigExtras.cmake"

  but not all the files it references.

今天在mac下安装 MARSYAS时出现了一个这样的问题。

这个是在安装QT时候没有配置好。我对qt还不是特别熟，只好先暴力解决这个问题。

先找到QtCore的配置文件：

/usr/local/lib/cmake/Qt5Core/Qt5CoreConfig.cmake

然后在下面这行中加入相应的路径。

原始路径：

get_filename_component(_qt5Core_install_prefix "${CMAKE_CURRENT_LIST_DIR}/../../../" ABSOLUTE)

修改后：

get_filename_component(_qt5Core_install_prefix "${CMAKE_CURRENT_LIST_DIR}/../../../Cellar/qt5/5.5.1_2/" ABSOLUTE)
