#276 cmake build fails with syntax error in VERSION script for libpng-1.6.34 shared

[Mario Emmenlauer]

I can build libpng successfully with the standard autotools. But I prefer cmake because I need to build on many architectures. The cmake build goes until 77%, but fails with an error in the VERSION script:

make[4]: Leaving directory '/tmp/debug-Ubuntu-16.04-x86_64-gcc5.4.0/thirdparty/libpng-1.6.34-x86_64'

Attached the version script. Is something fishy there?
