[devel] Various bugfixes and improvements to CMakeLists.txt (Philip Lowman)
1. Modify project(PNG) to project(PNG C) to avoid search for C++ compiler 2. set(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true) and fix end conditionals from ugly else(FOO AND BAR) endif(FOO AND BAR) to else() endif() 3. Add missing include_directories() for ZLIB_INCLUDE_DIR 4. Created CMake options to allow configurable building of STATIC or SHARED libpng, both default on. 5. Modified PNG_DEBUG to default to false? 6. Fix installation of static/shared libraries so DLL goes in prefix+/bin, all others in prefix+/lib
