Subject: [PATCH] cmake: don't wrap ZLIB_INCLUDE_DIR with BUILD_INTERFACE genex
When libpng is configured with awk available, the ZLIB_INCLUDE_DIR
variable is copied and used in a cmake script.
There, it is used as an argument to the C compiler.
Because script mode does not have a generator phase, don't use genex
variables here.
