Such a command, should it look something like this?

find_library(<VAR> libsndfile-1.dll [C:\Program Files\libsndfile])

What is <VAR> ? Should I give it a name, or leave it this way?

You put this in CMakeLists right?


When looking into the source (I'm not a developer) I find on this location:
lmms\cmake\modules

these files. It looks like the files are meant for finding stuff

BuildPlugin.cmake
ChecksForLibSamplerate.cmake
DetectMachine.cmake
FindAlsa.cmake
FindOggVorbis.cmake
FindPkgConfig.cmake
FindPortaudio.cmake
FindPulseAudio.cmake
FindSTK.cmake
InstallHelpers.cmake
Win32Toolchain.cmake
Win64Toolchain.cmake
cmakefiles
config-alsa.h.cmake
