lmms has some dependencies that are not so easy to determine for Fedora
Basic setup :

yum install cmake git
yum install qt qt-devel

Synth extras :

yum install libsndfile libsndfile-devel
yum install fluidsynth fluidsynth-devel
yum install stk stk-devel
yum install fftw-devel

yum install wine wine-devel
yum install glibc-devel.i386

Hope this helps

cd /usr/share/asterisk
rmdir sounds
ln -s /var/lib/asterisk/sounds .
