我正在尝试按照指南从源配置和构建 LMMS：
https://github.com/LMMS/lmms/wiki/dependency-windows#windows-msvc
我有
Windows 7 x64
2019年MSVC
Qt 5.15.1 x32 和 x64 以及 Qt Creator 4.13.2
CMake 3.16.1
首先，在末尾（我使用
--triplet x64-windows.\vcpkg install fftw3 libsamplerate libsndfile sdl2 --triplet x64-windows
我明白了
...
The package fftw3:x64-windows provides CMake targets:
find_package(FFTW3 CONFIG REQUIRED)
target_link_libraries(main PRIVATE FFTW3::fftw3)
find_package(FFTW3f CONFIG REQUIRED)
target_link_libraries(main PRIVATE FFTW3::fftw3f)
find_package(FFTW3l CONFIG REQUIRED)
target_link_libraries(main PRIVATE FFTW3::fftw3l)
The package libsndfile:x64-windows provides CMake targets:
find_package(SndFile CONFIG REQUIRED)
target_link_libraries(main PRIVATE SndFile::sndfile)
The package sdl2:x64-windows provides CMake targets:
find_package(SDL2 CONFIG REQUIRED)
target_link_libraries(main PRIVATE SDL2::SDL2 SDL2::SDL2main)
标题“需要配置”是否需要我在执行后续步骤之前执行一些操作？
按照说明所写，我将 vcpkg 路径添加到
CMAKE_PREFIX_PATH:STRINGCMAKE_PREFIX_PATH:STRING=%{Qt:QT_INSTALL_PREFIX};g:\audio_sources\lmms\vcpkg\installed\x64-windows
然后在 Qt Creator 中打开 CMakeLists.txt 时我得到：

CMake Deprecation Warning at CMakeLists.txt:15 (CMAKE_POLICY):
The OLD behavior for policy CMP0050 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

除此之外，在消息中我看到了这些行
The following plugins are not available:
LadspaEffect;zynaddsubfx
虽然
LadspaEffectzynaddsubfxplugins我做错了什么？
除了
pkg-configvcpkgpkg-config-lite-0.28-1作为参与 LMMS 团队的人，我可以说 ladspa amd zyn 被故意禁用（不过最近添加了 zyn 支持）。原因是这些插件包含一些仅限 Linux/GCC 的解决方法。 Windows 二进制文件实际上是从 ubuntu 交叉编译的。如果您想了解更多信息，请加入不和谐（LMMS 网站中的链接）。
编辑：到目前为止，我也已经打开了 Pull 请求来添加 LADSPA 支持。一旦合并就回来。
