This allows one to generate a header that will basically always work. In case
an unknown compiler or compiler version is encountered it simply falls back to
the unsupported case.

This allows a single condition to be used to choose between two
alternatives. Without this the condition must be duplicated with
one surrounded by `NOT`.
Closes: #15585
These new global properties were added:
* FeatureSummary_PKG_TYPES: Package types accepted by FeatureSummary
(default REQUIRED RECOMMENDED OPTIONAL RUNTIME).
* FeatureSummary_REQUIRED_PKG_TYPES: Package types that will cause
FeatureSummary to abort when called with
FATAL_ON_MISSING_REQUIRED_PACKAGES and a package in these categories
is missing (default REQUIRED).
* FeatureSummary_DEFAULT_PKG_TYPE: Default package type assigned when
not explicitly assigned by the user (default OPTIONAL).
This allows to add and remove new package types that can be printed
selectively using the "WHAT" argument.
The OPTIONAL type is used anyway as default when the type is not set
Since RUNTIME < OPTIONAL, forcing it here forces the user to set
"RUNTIME" at the first SET_PACKAGE_PROPERTIES, otherwise it is
impossible to set it later.
Without this it is impossible, for example, to add package information
(URL and DESCRIPTION) in the FindPackage file, but allow the package
to be RUNTIME.
At least the scratchbox compiler for the N900, which basically is a gcc 4.2,
sets only __GNUG__ in C++ mode, but not __GNUC__. It does indeed set
__GNUC_MINOR__ and __GNUC_PATCHLEVEL__. Extend the compiler detection code for
GNU compilers in C++ mode to look at __GNUG__ in case __GNUC__ is absent.

Currently, once pkg_check_modules succeeds, it will never call
_pkg_check_modules_internal again. That means that if the parameters
to pkg_check_modules are changed, cmake will be called to reconfigure,
but nothing will change. This change is to store the full string of
arguments to pkg_check_modules and override the FOUND optimization so
that the arguments are reevaluated when modified.
