Split the find_dependency macro into a separate file.

This allows Config file authors to use it without having to use
CONFIGURE_PACKAGE_CONFIG_FILE.
Help: Add missing period.
Help: Fix CMP0037 docs.

INTERFACE libraries may not use double-colons, but IMPORTED
targets may.
Constify cmStrCmp.
Genex: Allow single param expressions to accept arbirary input.

Existing single-parameter expressions work due to special casing
which assumes that if there is only one parameter, and the node
accepts arbitrary content, then the result is the input.

This is true for the existing expressions matching that
pattern - namely the "1" and "TARGET_NAME" expressions. However,
the LOWER_CASE, and UPPER_CASE expressions should also accept
arbitrary content, and in their case, the result is not the input.

Refactor the cmGeneratorExpressionEvaluator to allow that extension.
Actually evaluate the "1" and "0" nodes.
Genex: Accept arbitrary content in *_CASE and MAKE_C_IDENTIFIER.
Export: Clean up comment.

Introduced in commit a4263c9f (export(): Handle multiple dependent export
sets., 2013-10-10)
Genex: Always return immediately on error.
Genex: Use case-sensitive comparison in PLATFORM_ID.
Automoc: Fix style

Insert whitespace before operators.
cmTarget: Fix typo

'a ALIAS' -> 'an ALIAS'
FindBacktrace: Search and report only when not already found

Avoid saying "... detected in default set..." each time CMake is run.

Add MirBSD platform support (#14659)

Add a Modules/Platform/MirBSD.cmake module that just includes the
OpenBSD platform module.
Help: Clarify CMAKE_VERBOSE_MAKEFILE initialization (#14658)

Explain that it is initialized to false by the project() command and
intended for configuration by the end user performing a build.
Export: Skip INTERFACE libraries when generating -config files.

The properties object has just been created, so is always empty,
which means the if block is never entered. The following lines do
not have any effect because an INTERFACE library has no LOCATION.
At the end, no code is generated for INTERFACE libraries in
config-specific exported files, so skip them early.

Help: Mention if(POLICY) and NO_POLICY_SCOPE in policies manual.
