建立超级对撞机从源头，错误的版本qt。

Question

我有Linux 19，我真的很想安装SuperCollider。我不能用apt-get来做这件事，因为有些旧版本不支持SuperDirt.我需要从源头上建造它。我使用本指南：https://github.com/supercollider/supercollider/wiki/Installing-SuperCollider-from-source-on-Ubuntu问题与cmake：

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

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qt5.5.1 5.11，但是如何“显示”cmake，如果它自动检查具有qt5.5.1的/usr/lib/./ Qt 5的路径，就应该使用qt5.11？我该怎么办？

将CMAKE_PREFIX_PATH设置为Qt安装中包含bin、lib、include等的目录。通常如下所示：

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