As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.
The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.
Clang can compile code, but uses the gcc tools for other tasks such
as linking. The -gcc-toolchain option can be used for that, but
generalize so that other compilers can be treated the same.
If such a location is specified, use it as a hint for finding
the binutils executables.
For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like
set(triple arm-linux-gnueabihf)
set(CMAKE_C_COMPILER "/usr/bin/clang")
set(CMAKE_C_COMPILER_TARGET ${triple})
set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
set(CMAKE_CXX_COMPILER_TARGET ${triple})
or
set(arch gcc_ntoarmv7le)
set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
set(CMAKE_C_COMPILER_TARGET ${arch})
set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
set(CMAKE_CXX_COMPILER_TARGET ${arch})
Both clang and qcc are inherently cross compiler( driver)s.
When cross-compiling with clang, use the CMAKE_${lang}_COMPILER_TARGET
as the _CMAKE_TOOLCHAIN_PREFIX to find the appropriate binutils.
When cross-compiling with QNX qcc, use the CMAKE_${lang}_COMPILER_TARGET
to set the appropriate _CMAKE_TOOLCHAIN_PREFIX.
The find_file this module uses to locate the compiler id source file
must always look on the host and never in CMAKE_FIND_ROOT_PATH, even
when a toolchain file has
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
Add NO_CMAKE_FIND_ROOT_PATH to the find_file call to avoid rerooting.
Since commit 7d47c693 (Drop compatibility with CMake < 2.4, 2013-10-08)
we no longer need to use the configure_file IMMEDIATE option to support
compatibility modes less than 2.0.
Allow ExternalData_URL_TEMPLATES to be empty if a value for
ExternalData_OBJECT_STORES is provided. Assume in this use case that
the object stores will already contain all needed objects. Extend the
Module.ExternalData test to cover this case (all objects in stores).
Extend the RunCMake.ExternalData test to cover the non-failure message
case when stores are provided without URL templates.
Manually revise the .rst format of the documentation. Use inline
literal quotes appropriately in paragraph text. Move the :: literal
block openers to the end of the preceding paragraphs. Convert the
command signature documentation and examples to cmake code-block
directives.
On biarch architecture, CMAKE_SYSTEM_PROCESSOR might be a 64bit one
while the system 32bit one. Take this into consideration while looking
for Java library directory.

The set() call for this variable left out the CACHE keyword. It does
not need to be cached anyway, so drop the other CACHE set() signature
arguments.

As mentioned in commit 4693cf84 (Xcode: Detect new default locations of
Xcode 4.3 bits and pieces) PackageMaker was split out of Xcode 4.3 and
above into a separate Auxiliary tools package. Since Xcode 5.0 or so,
Apple no longer distributes PackageMaker as part of the available
development tools so it can only be obtained from old packages.
Disable the CPACK_BINARY_PACKAGEMAKER option by default as is the case
for most other tool-dependent generators.
In certain scenarios, it is preferable to keep a 'dirty' install prefix
than to clear it, and to expect that content will not be found there.
Add a CMAKE_FIND_NO_INSTALL_PREFIX variable that can be set to disable
searching the install prefix.

3e04946 Require CMAKE_<LANG>_COMPILER to be found as a full path
6007f7c CMakeDetermineCompilerId: Always use compiler detected from IDE
332771c CMakeDetermine*Compiler: Remove temporary cache entry
All generators now support detection of the full path to the compiler, so
require it to be so. This will allow CMake<LANG>Information.cmake and
other logic to assume the full path to the compiler tool is available.
The Makefile generators already rejected CMAKE_<LANG>_COMPILER values
that did not name an existing compiler. Extend this error message to
all generators, make it occur as early as possible, and improve the
message with advice about how to set the compiler. If the full path to
the compiler is not known, finish enabling languages with a fatal error
so configuration does not continue.
For now, allow the RC language compiler to not be a full path. Later we
will need to detect the full path to "rc" under the VS IDE.
Add a RunCMake.CompilerNotFound test to cover failure cases.
Fix the RunCMake.CompilerChange test EmptyCompiler case to work
when configuration does not continue past enable_language.
When compiler id detection also provides a CMAKE_<LANG>_COMPILER
value, use it unconditionally. It is known to be the compiler
that is actually in use by IDE builds in VS and Xcode. Do not
let a stray cache entry try to say otherwise.
Teach the ctest_update implementation to use the p4 command-line
client to perform updates and extract the list of changes.
Add a CTest.UpdateP4 test like those that exist already for the other
version control tools. Make the test available when p4 and the p4d
server are found. During the test launch p4d in the background to
serve a repository from the test directory. Then direct the client
toward this server for the duration of the test.
One way to use clang as a cross-compiler is to create
a symlink named <target>-clang, which is equivalent to
running
clang -target <target>
Extract the toolchain prefix to find the binutils executables.
When the user or toolchain file sets CMAKE_<LANG>_COMPILER to a name
without a path we use find_program with CMAKE_<LANG>_COMPILER_WITH_PATH
to search for the tool. Remove the temporary cache entry afterward to
avoid exposing it to projects. It is not set by other logic paths so no
one should be using it.
