找不到Qt6安装吗？

Question

尝试遵循GitHub页面的安装说明：https://github.com/TASEmulators/fceux

我一直在安装Qt6，当我这样做时，会发生以下情况：

mkdir build
cd build
cmake  -DCMAKE_INSTALL_PREFIX=/usr  -DQT6=1  -DCMAKE_BUILD_TYPE=Debug    ..

-- Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.19042.
-- GUI Frontend: Qt6
CMake Error at src/CMakeLists.txt:22 (find_package):
  By not providing "FindQt6.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt6", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt6" with any of
  the following names:

    Qt6Config.cmake
    qt6-config.cmake

  Add the installation prefix of "Qt6" to CMAKE_PREFIX_PATH or set "Qt6_DIR"
  to a directory containing one of the above files.  If "Qt6" provides a
  separate development package or SDK, be sure it has been installed.

正如错误消息所述，您需要将环境值Qt6_DIR设置为安装qt6的位置。这应该是安装qt6的说明的一部分。

您应该链接用于安装qt6的说明。它们可能包含设置环境变量QT_DIR的指令，而不是正在构建的Qt6_DIR。如果是这样的话，只需按照设置QT_DIR的说明来设置Qt6_DIR。
