Remove ancient checks left from commit f5d95fb0 (Complete rework of
makefile generators expect trouble, 2002-11-08). Modern FreeBSD and
NetBSD platforms support shared libraries. When cross-compiling the
/usr/include/dlfcn.h may not exist on the host but the toolchain still
supports shared libraries.
The changes in "use PATH_SUFFIXES to simplify find_* calls" on 8/14
regressed important functionality in FindGTK for using find_path to
locate header files in <prefix>/lib/<gtk_package>/include.
The find_path function doesn't search <prefix>/lib only <prefix>/include.
1e47ccb Ninja: add option to enforce usage of response files
e31df03 Ninja: move <OBJECTS> in front of the first linker option
8d674e7 Ninja: move -LIBPATH behind -link option
In the response file also linker options could be passed,
and because <OBJECTS> is replaced by a response file, it
is necessary that no compiler option follows <OBJECTS>.
This reverts commit 5598d9b2a0.
Since commit f1670ab1 (Ninja: don't confuse ninja's rsp files with
nmake's, 2012-09-26) Ninja generator response files are placed in
CMakeFiles/ so the previously existing check already avoids expanding
them.

Write new documentation for this module. Ensure that it formats
correctly in "cmake --help-module FindBoost" output. Show the basic
form of calling find_package(Boost). Document all result variables,
input variables, and cache variables appropriately grouped together.
Explain the search process and how it re-runs when changes are made.
Explain the difference between finding headers/libraries versus finding
a "Boost CMake" package configuraiton file.
Drop the emphasis on Boost_ADDITIONAL_VERSIONS because the
implementation should predict most future versions instead.
Construct an initial Boost_FOUND value immediately after searching for
Boost_INCLUDE_DIR. Base the result only on whether header files for the
requested version were found. Then after searching for component
libraries update Boost_FOUND based on whether all requested components
were found.
Construct the value from scratch based on the component library list.
Avoid accumulating values from repeated find_package(Boost) calls.
If Boost is not found, Boost_LIBRARIES should be empty.
Overhaul the implementation as follows:
(1) Do not cache result variables such as Boost_VERSION,
Boost_LIB_VERSION, Boost_LIBRARY_DIRS, Boost_${COMPONENT}_FOUND,
Boost_${COMPONENT}_LIBRARY, or Boost_LIB_DIAGNOSTIC_DEFINITIONS that are
derived uniquely from other search results. The user should not edit
them anyway.
(2) Add cache value Boost_LIBRARY_DIR to hold the single directory
expected to contain all libraries. Once one library is found, search
only that directory for other libraries.
(3) Use the find_library NAMES_PER_DIR option to consider all possible
library names at the same time.
(4) Collect all documented input and cache variables and detect when
they have been changed by the user. Discard prior search results that
may have been influenced by the changes and search for them again.
Environment variables are not expected to be persistent so use them only
as hints and do not consider changes to them to be meaningful.
The CMake find_path command looks under the proper "Program Files"
directories on Windows with any of the provided PATH_SUFFIXES. This is
simpler and more robust than directly reading ENV{ProgramFiles}. Once
Boost_INCLUDE_DIR has been located we already look next to it for the lib
directory anyway, so we do not need special help to find Boost libraries
under "Program Files".
Since FPHSA is called for multiple compiler languages with "MPI_${lang}"
rather than just "MPI", make sure variables for controlling QUIET,
REQUIRED and VERSION are propagated with names prefixed by MPI_${lang}
as well, rather than just MPI.
The find_package call sets up the values of MPI_FIND_REQUIRED and friends,
but these calls to FPHSA need MPI_${lang}_FIND_REQUIRED and friends in
order to function as intended.

Furthermore, format the documentation.
Since commit 1786b121 (OS X: Allow CMAKE_OSX_SYSROOT to be a logical SDK
name, 2012-09-21) we support names like "macosx" or "macosx10.7" as the
specified value of CMAKE_OSX_SYSROOT. Extend the SDK name->path
conversion to save the original value and also convert into a temporary
variable for the Xcode generator. Re-implement the deployment target
sanity check to detect the version from the transformed path.
Since commit 230ea218 (OS X: Improve default CMAKE_OSX_SYSROOT
selection, 2012-09-21) we always set CMAKE_OSX_SYSROOT if any SDK is
found in order to support Makefile generator builds with Xcode >= 4.3
without the command-line tools installed. However, in the basic
POSIX-only case of the Makefile generator with command-line tools and no
CMAKE_OSX_ARCHITECTURES we should not select any SDK by default.
Xcode supports SDKROOT values that just name an SDK rather than
specifying the full path to it. Recognize these values and handle them.
For Xcode we just put the value directly in the generated project file.
For Makefile generators we ask xcodebuild to provide the full path to
the named SDK.

Simplify the search for OSX_DEVELOPER_ROOT and allow it to fail if no
"/Developer" exists. When it does exist, always find a MacOSX SDK
inside it to use as the default CMAKE_OSX_SYSROOT. Otherwise set
CMAKE_OSX_SYSROOT to empty.
Drop the last use of CMAKE_OSX_SYSROOT_DEFAULT. Replace internal
platform variable CMAKE_${lang}_HAS_ISYSROOT with a more general
CMAKE_${lang}_SYSROOT_FLAG variable. If the -isysroot flag exists and
CMAKE_OSX_SYSROOT points to an SDK (not "/") then always add it to
compiler command lines. This is already done in the Xcode IDE.
The GNU compiler information file tests for GNU >= 3.4 because earlier
versions do not have the flag. The version number test is not valid for
Clang compiler versions, but we know Clang supports the flag.
While Clang presents an almost identical interface to GNU there will be
some differences. Split the compiler information modules to allow
separate rules for Clang. Start by loading the GNU rules but leave a
place to add Clang-specific information.
Make the EXPECTED_HASH option take only a single value instead of two to
avoid handling sub-keyword arguments. This is also consistent with
URL_HASH in ExternalProject.
Some download URLs do not have the filename embedded in the url.
Add an interface to specify the local filename explicitly.

Use the registry entries that vsvars32.bat uses to detect the location of
MSBuild.exe in the framework directory. Invoke MSBuild with the option
/p:VisualStudioVersion=$version
so it knows from which VS version to load the system build rules. Teach
cmGlobalVisualStudio11Generator to set its ExpressEdition member using the
registry.
Clang has the same interface as GNU except that we do not need to test
for the deployment target and sysroot flags. Simply set variables
CMAKE_${lang}_HAS_ISYSROOT
CMAKE_${lang}_OSX_DEPLOYMENT_TARGET_FLAG
to true because every version of Clang available on OS X supports these
flags.
TLS has superseded SSL so rename the recently added file(DOWNLOAD) and
ExternalProject options using the newer terminology. Drop "CURLOPT"
from names because curl is an implementation detail.
This commit adds the ability to turn on and off ssl certificate
authority checking. It also adds the ability to specify a
certificate authority information file. This can be done
by setting global cmake variables CMAKE_CURLOPT_CAINFO_FILE
and or CMAKE_CURLOPT_SSL_VERIFYPEER in the project calling
ExternalProject_Add, or by passing those options to individual
ExternalProject_Add calls.
This triggered an unknown secondary bug when there is
no ABSOLUTE INSTALL file. This is fixed as well.
This is based on a fix of bug #0013468 from Viktor Dubrovsky.
...if the library file does not exist inside the .framework then do
not allow a library variable to be set to the path to the framework.
Force set it to NOTFOUND instead.
This enables CMake to create Makefiles targeting Windows CE devices.
CMake needs to be run within a cross compile command prompt and requires
a toolchain file which sets CMAKE_SYSTEM_NAME to "WindowsCE" and
optionally CMAKE_SYSTEM_VERSION.
In commit 485a940e (VS: Simplify MSVC version reporting, 2012-08-23) we
accidentally flipped the 0/1 values of MSVC_IDE. Flip them back and
teach the CheckCompilerRelatedVariables test to check the variable.

7195aca Make platform information files specific to the CMake version
Remove the old-style "Windows-cl.cmake" and its helper "cl.cmake". Load
the information through new-style "Platform/Windows-MSVC-<lang>.cmake"
files. Factor information common to C and CXX into a helper file
"Platform/Windows-MSVC.cmake" loaded from the per-language files.
Teach Windows-cl.cmake to use CMAKE_(C|CXX)_COMPILER_VERSION to set the
"MSVC##" and MSVC_VERSION variables. It no longer needs the IDE generator
to dictate the version or to detect the version by running the
command-line tool for NMake and Ninja generators. Drop configuration of
CMakeCPlatform.cmake and CMakeCXXPlatform.cmake from Windows-cl.cmake.in
because all the results it saved are now cheap to compute every time.
Drop use of cache entry CMAKE_DETERMINE_<LANG>_ABI_COMPILED and replace
it with variable CMAKE_<LANG>_ABI_COMPILED. Since the grandparent
commit this test result is specific to the version of CMake. Store it
in the version-specific compiler information files instead of
CMakeCache.txt so testing can be re-done to meet the requirements of the
current version of CMake even if another version of CMake was already
used to configure the build tree.

Since the parent commit this test result is specific to the version of
CMake. Store it in the version-specific compiler information files
instead of CMakeCache.txt so testing can be re-done to meet the
requirements of the current version of CMake even if another version of
CMake was already used to configure the build tree.
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use. The
method of detection and the exact results store varies across CMake
versions as things improve. This leads to problems when loading files
configured by a different version of CMake. Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files. This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).
Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version. Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake. Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.
Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose. The new variable points
at the version-specific directory while the old variable did not.
Several more recent Visual Studio Express editions are now available and
they support debug builds. Simplify our VS platform files by removing
support for these old tools. If anyone still uses them we can restore
support with a more modern way to test for them.
Configure a hand-generated Visual Studio project to build the compiler id
source file since we cannot run the compiler command-line tool directly.
Add a post-build command to print out the full path to the compiler tool.
Parse the full path to the compiler tool from the build output.
Configure a hand-generated Xcode project to build the compiler id source
file since we cannot run the compiler command-line tool directly. Add a
post-build shell script phase to print out the compiler toolset build
setting. Run xcodebuild to compile the identification binary. Parse
the full path to the compiler tool from the xcodebuild output.
Teach CMAKE_DETERMINE_COMPILER_ID to check for variable
CMAKE_${lang}_COMPILER_ID_TOOL after CMAKE_DETERMINE_COMPILER_ID_BUILD
to use as CMAKE_${lang}_COMPILER since it will not be known until after
the IDE runs.
In CMAKE_DETERMINE_COMPILER_ID_BUILD prepare a cascading "if" so we can
use a generator-specific method to compile the identification source
file. Leave "if(0)" as a placeholder for now and put the direct
compiler invocation in "else()". After running the compiler to build
the compiler identification source we file(GLOB) the list of output
files as candidates for extracting the compiler information. An IDE may
create directories, so exclude exclude directories from this list.
Re-organize CMakeDetermine(C|CXX|Fortran)Compiler.cmake to search for
the compiler command-line tool only under generators for which it makes
sense. For the Visual Studio generators we do not expect to find the
compiler tool from the environment, nor would we use the result anyway.
Furthermore, set CMAKE_${lang}_COMPILER_ID_TEST_FLAGS only when it has a
chance to be used. Extract _CMAKE_TOOLCHAIN_LOCATION from the compiler
path after running the compiler id step so in the future that step can
help find the path to the compiler.
Commit 4be67837 (read less from version headers into variables,
2012-08-19) switched from file(READ) and string(REGEX MATCHALL) to just
file(STRINGS) to extract the list of resource <file> entries. However,
the latter extracts entire lines that match the regex, not just the part
that matches the regex, so the subsequent string(REGEX REPLACE) fails to
match and replace anything. Return to the original parsing logic but
replace file(READ) with file(STRINGS) to load a minimal part of the file
before using string(REGEX MATCHALL) as before.
Added a new CUDA variable for specifying the CUDA_HOST_COMPILER. This will allow users to
be able to specify which host compiler to use for invoking NVCC with. By default it will
use the compiler used for host compilation. This is convenient for when you want to
specify a different compiler than the default compiler. You end up using the same
compiler for both the NVCC compilation and the host compilation instead of using the
default compiler in the path for NVCC.
