Clang points out that local variable 'seed' needs to be "unsigned int":
Source/cmStringCommand.cxx:828:21: warning: operands of ? are integers
of different signs: 'int' and 'unsigned int' [-Wsign-compare]
srand(force_seed? seed : cmSystemTools::RandomSeed());
^ ~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
Use static_cast to avoid warnings like
conversion to ‘unsigned int’ from ‘__time_t’ may alter its value
conversion to ‘unsigned int’ from ‘__suseconds_t’ may alter its value
We do not care if the value is truncated because we are looking for just
32 bits anyway.
The naive time(0) seed is unique only within one second. Instead try to
read a real source of entropy and otherwise fall back to a combination
of the process id and high-resolution time.
Under Windows "locationURI" must be used for virtual folders, while
"location" must be used only for linked folders. Under Linux it doesn't
seem to matter.

The system package registry is under HKEY_LOCAL_MACHINE\SOFTWARE which
has separate views for 32-bit and 64-bit applications. Look in both
views, but prefer the architecture matching the build target platform.
Generalize the "user package registry" created by commit ed0650f6 (Teach
find_package to search a "package registry", 2009-09-01). Define a
corresponding "system" registry key under HKEY_LOCAL_MACHINE. This
gives package installers a place to create a registry value that points
at the right location for find_package() to locate the package.
