The original value is saved in `_pkg_config_path_old`. Fix this typo
left by commit v3.1.0-rc1~763^2 (FindPkgConfig: Extend PKG_CONFIG_PATH
using CMake variables, 2014-03-06).
Some compilers may add their own RPATH entries when invoking the linker.
For example, a GCC installation may contain the following definition in
the specs file:
*link_libgcc:
%D -rpath <<some specific rpath in which libstdc++.so can be found>>
In this case binaries may contain RPATH entries that CMake did not add.
When we update the RPATH on installation we must preserve these entries
even if CMake thinks the INSTALL_RPATH value should be empty.
Fix this by always using file(RPATH_CHANGE) and teach it to behave as
file(RPATH_REMOVE) if the actual RPATH in the file is empty after
replacing the build-tree RPATH with the install-tree RPATH. This will
preserve any compiler-added RPATH value instead of removing it.
In Modules/Platform/WindowsPaths.cmake our previously recorded
environment variable combinations no longer seem to be correct. For
example, a 64-bit cmake binary may see ProgramW6432 in the environment
and end up not considering the "ProgramFiles(x86)" variable. Instead
check for all possible environment variables in the preferred order and
then remove duplicates.

The target_link_libraries command records the PRIVATE dependencies of a
STATIC library in INTERFACE_LINK_LIBRARIES as "$<LINK_ONLY:dep>". This
hides the target name from export namespacing logic inside a generator
expression. When user-written generator expressions reference a target
name they must put it inside a "$<TARGET_NAME:dep>" expression to allow
the export logic to rename the target. In the case that the private
dependency is not already a generator expression, target_link_libraries
must use "$<LINK_ONLY:$<TARGET_NAME:dep>>" to allow the export logic to
rename the target.

Add `VERBATIM` to all `add_custom_command` calls so that CMake will
escape arguments properly even when special characters such as "()" are
present.

Since commit v3.3.0-rc1~410^2~3 (ctest_test: Add QUIET option,
2015-02-17) if tests fail when QUIET is used one sees:
The following tests FAILED:
but not the subsequent line(s) indicating which tests failed.
Restore the list of failed tests.
Expand the -W set of cmake options to include support for the -Werror
and -Wno-error format, which is used to control upgrading and
downgrading warning and error messages. Implement support for these new
formats for the dev and deprecated message types.
Add tests and updated documentation for new options.
Most packages install their .pc files into PREFIX/lib/pkgconfig, but
some put them into PREFIX/share/pkgconfig. Either is valid, and
pkg-config itself looks in both for the /usr and /usr/local prefixes.
This fixes an issue where some packages (yajl, for example) are not
found if they are installed into a non-standard prefix and
CMAKE_PREFIX_PATH is used to locate them.
