从源代码构建 Supercollider，qt 版本错误。

Question

我有 Linux Mint 19，我真的很想安装 SuperCollider。我不能通过 apt-get 做到这一点，因为有不支持 SuperDirt 的旧版本。我需要从源代码构建它。我使用本指南： https://github.com/supercollider/supercollider/wiki/Installing-SuperCollider-from-source-on-Ubuntu cmake 有问题：

cmake -qt=qt5.11 -DSC_EC=ON -DSC_EL=OFF -DSC_WII=OFF -DSC_IDE=ON ..
-- SuperCollider Version: 3.10.0-beta2
-- Building from branch develop, commit hash is f543f53
-- Build type defaulting to "RelWithDebInfo"
-- Compiling with Qt GUI
-- building boost libraries manually
-- using bundled libyaml-cpp
-- HIDAPI components:
--     linux hidraw
-- libudev stable: 1
-- Found UDev: /usr/lib/x86_64-linux-gnu/libudev.so
--    include: /usr/include
--     hidapi_parser
-- Building with HID support
-- Using fftw3f
-- Found jack: /usr/lib/x86_64-linux-gnu/libjack.so
-- Audio API: jack
-- Found GNU Readline version 6.3: /usr/lib/x86_64-linux-gnu/libreadline.so
CMake Error at QtCollider/CMakeLists.txt:3 (find_package):
  Could not find a configuration file for package "Qt5" that is compatible
  with requested version "5.7".

  The following configuration files were considered but not accepted:

    /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.5.1

  lang/CMakeLists.txt:155 (include)

所以我至少需要 qt5.7，但我有 qt5.5.1 我不知道如何更新 qt。我安装了 Qt Creator 5.11，但是我如何 "show" cmake 我应该使用 qt5.11，如果它自动检查路径 /usr/lib/.../qt5 其中有 qt5.5.1？我该怎么办？

将 CMAKE_PREFIX_PATH 设置为包含 bin、lib、include 等的 Qt 安装目录。它通常如下所示：

cmake -DCMAKE_PREFIX_PATH=/opt/Qt/5.11.2/gcc_64 ...
