Read zlib.h by using file(STRINGS.....REGEX) to limit the amount of text we apply the version regex on. This patch also addresses the fact that the version string may contain a tweak component.
Patch by Simone Rossetto
Some zlib.h files have ZLIB_VERSION "1.2.3.3" with 4 numbers instead of 3.
The regex is changed to grab the first 3 numbers.
It was slow because if it failed to find that string near the top of the file,
where it usually is, it would read the entire file.
This adds copyright/license notification blocks CMake's find-modules.
Many of the modules had no notices at all. Some had notices referring
to the BSD license already. This commit normalizes existing notices and
adds missing notices.
FIND_PACKAGE_HANDLE_STANDARD_ARGS(), so cmake modules can specify their own
better failure messages. If the default is ok use "DEFAULT_MSG".
Do this also for FindBoost.cmake (#5349)
