If only it were that simple; the build system upstream has been a mess. The 
author only supports a manually written makefile, which did not build the 
shared libs until recently. There is also a cmake system which has built the 
shared libs for a while, but does not build the "lz4" executable that uses a 
similar command line interface as other compression tools. Then there was talk 
of adding an autotools system as well for some unknown reason. What each distro 
has depends on which build system they choose.
Now that both the manual makefile and the cmake system both build a shared lib, 
it should be possible to switch to it, but not until all (most) distros 
upgrade.
