The previous change to test finding in lib/cmake/<name>* weakened the
versioned find tests. Since the lib/cmake paths are searched before
lib/<name>* paths the previous change skipped requiring the command to
ignore zot-3.0 when finding zot-3.1. This change restores that and adds
zot-4.0 to test the lib/cmake path.
This teaches find_package to search
<prefix>/(share|lib)/cmake/<name>*/
for package configuration files. Packages that do not already have
files in a <prefix>/lib/<name>* directory can use this location to avoid
cluttering the lib directory.
- Added EXACT option to request an exact version.
- Enforce version using check provided by package.
- Updated FindPackageTest to test versioning in config mode.
