[PATCH] lzo: switch to building with CMake

[Rosen Penev]

CMake is less error prone that autotools and also compiles faster.

Fixed license information.

Added pkgconfig file to InstallDev so that packages that use it can
find lzo.

Before:

time make package/lzo/compile -j 12
________________________________________________________
Executed in   20.87 secs   fish           external
   usr time   26.95 secs    0.00 micros   26.95 secs
   sys time    5.49 secs  305.00 micros    5.49 secs

After:

time make package/lzo/compile -j 12
________________________________________________________
Executed in   13.22 secs   fish           external
   usr time   19.59 secs  328.00 micros   19.59 secs
   sys time    4.03 secs   10.00 micros    4.03 secs

Time output is with fish shell. make clean was ran before both attempts.
