Matt McCormick 3816cd2dc7 FindPythonLibs: Find consistent Python interp, headers, libs (#13794)
When possible, get consistent version of the Python interpreter, headers path,
and library.

Now find_package(PythonLibs) internally calls find_package(PythonInterp
QUIET) and uses the resulting PYTHON_VERSION_MAJOR and
PYTHON_VERSION_MINOR to prefer these versions when looking for the
header path and library.  The Python_ADDITIONAL_VERSIONS variable has
priority over the interpreter version.

CMake already provides the version components split into variables, no need to

Rolf Eike Beer 8ebf74b02f Find* (and some other): use ${CMAKE_CURRENT_LIST_DIR} in include()
This solves a lots of warnings, e.g. in the FindModulesExecuteAll test. If the
installed version on the system is rather old this may even lead to bugs, e.g.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command

Run the following shell code:

grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'

Ben Boeckel 4bdec581b3 Search for other ABIFLAGS builds of Python
Starting with Python3, standard Python installs may have additional ABI
flags attached to include directories and library names. As of 3.2, the
following flags are in the configure file:

    d -> --with-debug
    m -> --with-pymalloc
    u -> --with-wide-unicode

Python 3.3 seems to no longer have --with-wide-unicode. Hopefully Python
will ensure that the possible flags always show up in a stable order.
The 'd' flag is ignored since the debug library is considered separate.

There is still the problem where ABI flags cannot be specified in
find_package since the letters confuse the version comparator.

Ben Boeckel 6a46f5ce80 Don't put legacy variables back into the cache
If PYTHON_INCLUDE_PATH is put into the cache, then it will always
override whatever might be found and PYTHON_INCLUDE_DIR is never given a
chance to find something different. It being marked as INTERNAL also
means that it cannot be changed without editing CMakeCache.txt directly.

Basically, the scenario is that if the Python version is changed, then
deleting PYTHON_INCLUDE_DIR doesn't work because any cached
PYTHON_INCLUDE_PATH variable is set before find_path is even called. Any
build tree using a previous version will still need either manual
removal of PYTHON_INCLUDE_PATH or a complete reconfigure, but in the
future changing the Python version can be accomplished by deleting
PYTHON_INCLUDE_DIR and reconfiguring with the new version.

Christian Andersson a04ced3b38 FindPythonLibs: Search for single-user installs on Windows
When cmake searches for Python libs in Windows it searches in:

  [HKEY_LOCAL_MACHINE\\SOFTWARE\\Python\\PythonCore\\${_CURRENT_VERSION}\\InstallPath]/libs

However, the information might not always reside there.  The information
could also reside in:

  [HKEY_CURRENT_USER\\SOFTWARE\\Python\\PythonCore\\${_CURRENT_VERSION}\\InstallPath]/libs

when one installs Python for a single user and not for all users.

Brad King c4275592a8 Modules: Include builtin FindPackageHandleStandardArgs directly
The FindPackageHandleStandardArgs module was originally created outside
of CMake.  It was added for CMake 2.6.0 by commit e118a627 (add a macro
FIND_PACKAGE_HANDLE_STANDARD_ARGS..., 2007-07-18).  However, it also
proliferated into a number of other projects that at the time required
only CMake 2.4 and thus could not depend on CMake to provide the module.
CMake's own find modules started using the module in commit b5f656e0
(use the new FIND_PACKAGE_HANDLE_STANDARD_ARGS in some of the FindXXX
modules..., 2007-07-18).

Then commit d358cf5c (add 2nd, more powerful mode to
find_package_handle_standard_args, 2010-07-29) added a new feature to
the interface of the module that was fully optional and backward
compatible with all existing users of the module.  Later commit 5f183caa
(FindZLIB: use the FPHSA version mode, 2010-08-04) and others shortly
thereafter started using the new interface in CMake's own find modules.
This change was also backward compatible because it was only an
implementation detail within each module.

Unforutnately these changes introduced a problem for projects that still
have an old copy of FindPackageHandleStandardArgs in CMAKE_MODULE_PATH.
When any such project uses one of CMake's builtin find modules the line

  include(FindPackageHandleStandardArgs)

loads the copy from the project which does not have the new interface!
Then the including find module tries to use the new interface with the
old module and fails.

Whether this breakage can be considered a backward incompatible change
in CMake is debatable.  The situation is analagous to copying a standard
library header from one version of a compiler into a project and then
observing problems when the next version of the compiler reports errors
in its other headers that depend on its new version of the original
header.  Nevertheless it is a change to CMake that causes problems for
projects that worked with previous versions.

This problem was discovered during the 2.8.3 release candidate cycle.
It is an instance of a more general problem with projects that provide
their own versions of CMake modules when other CMake modules depend on
them.  At the time we resolved this instance of the problem with commit
b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake
everywhere, 2010-09-28) for the 2.8.3 release.

In order to address the more general problem we introduced policy
CMP0017 in commit db44848f (Prefer files from CMAKE_ROOT when including
from CMAKE_ROOT, 2010-11-17).  That change was followed by commit
ce28737c (Remove usage of CMAKE_CURRENT_LIST_DIR now that we have
CMP0017, 2010-12-20) which reverted the original workaround in favor of
using the policy.  However, existing project releases do not set the
policy behavior to NEW and therefore still exhibit the problem.

We introduced in commit a364daf1 (Allow users to specify defaults for
unset policies, 2011-01-03) an option for users to build existing
projects by adding -DCMAKE_POLICY_DEFAULT_CMP0017=NEW to the command
line.  Unfortunately this solution still does not allow such projects to
build out of the box, and there is no good way to suggest the use of the
new option.

The only remaining solution to keep existing projects that exhibit this
problem building is to restore the change originally made in commit
b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake
everywhere, 2010-09-28).  This also avoids policy CMP0017 warnings for
this particular instance of the problem the policy addresses.

Alex Neundorf ce28737c93 Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017
This puts the new search behaviour for included files in action, i.e.
now when a file from Modules/ include()s another file, it also gets the
one from Modules/ included, i.e. the one it expects.
