The old version would admit, for example, a variable named "xxxCPACK".

LANGUAGE should be ignored when LC_ALL=C.
It seems this isn't the case with hg so set both.

ARGV# could be defined from a parent scope.

If LC_ALL is set it takes precedence over LC_MESSAGES.

A more-specific error message is always displayed earlier in the
output if any real error occurred.  This final summary message
is distracting to readers searching through the output for the
word "error".  Simply drop it.

Use test infrastructure added by commit 1cbb1562 (Fix handling of
relocation prefix parent directories, 2015-02-26) to cover the same use
cases from tests added by commit 5857ca5e (CPackRPM: Drop explicit
handling of '@' symbols that breaks them, 2015-01-07) and drop the
latter.

Resolve conflict in Tests/CPackComponentsForAll/RunCPackVerifyResult.cmake
by combining the changes from both sides.

In commit 3ec02547 (CPackRPM: Allow multiple path relocation prefixes
for one package, 2015-01-21) a regression was introduced that causes
parent directories of relocation paths to be incorrectly included in
the rpm.  Fix this and make the test case more strict to cover it.

Avoid a separate open/close for each file installed.  Use a single
file(WRITE) instead of a loop with file(APPEND).

The Ninja build system does not support a in-file verbositiy switch.
Instead teach 'cmake --build' to extract the CMAKE_VERBOSE_MAKEFILE
setting and pass it as an optional '-v' argument to Ninja.  This can
serve as a reasonable fallback.

772eae44 RC: Add platform-specific preprocessor definitions (#15404)
4300de3e RC: Enable language after C, CXX, or Fortran is enabled (#15404)
1de4a0fb RC: Drop unused CMAKE_COMPILE_RESOURCE variable setting

f7f4ca55 ExternalData: Add support for custom algorithm-to-URL mapping

In Platform/Windows-MSVC the C and CXX flags are initialized to
contain preprocessor definitions describing the platform.  On
WinCE platforms this may not be just -DWIN32.  This information
may be important to RC sources too, so add such preprocessor
definitions to the default RC flags.
Suggested-by: Gunnar Roth <gunnar.roth@gmx.de>

The RC language is special in that it is automatically enabled
on Windows-based platforms when another primary language is
enabled.  Move enablement of RC from early in the enablement
of the other language to late.  This will allow it to use
information detected as part of enabling C, CXX, or Fortran.
