Explored some more, to solve the issue:

First maybe this is interesting:

$ pkg-config --libs sndfile
Package sndfile was not found in the pkg-config search path.
Perhaps you should add the directory containing `sndfile.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sndfile' found


Besides that, I found a FindSndfile.cmake file on the internet (see 
attachment)

I put it in lmms\cmake\modules

And added these entries in the cmake gui:

SNDFILE_INCLUDE_DIR               C:/Program 
Files/Mega-Nerd/libsndfile/include
SNDFILE_LIBRARY                         C:/Program 
Files/Mega-Nerd/libsndfile

But same error:

Found Qt-Version 4.5.2
checking for module 'sndfile>=1.0.11'
  package 'sndfile>=1.0.11' not found
CMake Error at cmake/modules/FindPkgConfig.cmake:270 (message):
  A required package was not found
Call Stack (most recent call first):
  cmake/modules/FindPkgConfig.cmake:322 (_pkg_check_modules_internal)
  CMakeLists.txt:116 (PKG_CHECK_MODULES)


CMake Error at CMakeLists.txt:118 (MESSAGE):
  LMMS requires libsndfile1 and libsndfile1-dev >= 1.0.11 - please install,
  remove CMakeCache.txt and try again!


Configuring incomplete, errors occurred!


I don't know if I have to change something to CMakeLists
