Insert application version into a source code file.

In the template file <input-file> the placeholders get replaced with version information and the result
is written to <output-file>. If <input-file> is not absolute it is interpreted relative to ${CMAKE_CURRENT_SOURCE_DIR},
if <output-file> is not absolute it is interpreted relative to ${CMAKE_CURRENT_BINARY_DIR}.
The <input-file>, <output-file> get added as source to <target>.
