Thanks, Thomas!
See the newly added documentation of the FOLDER target
property for details.
Also added global properties, USE_FOLDERS and
PREDEFINED_TARGETS_FOLDER. See new docs here, too.
By default, the FOLDER target property is used to organize
targets into folders in IDEs that have support for such
organization.
This commit adds "solution folder" support to the Visual
Studio generators. Currently works with versions 7 through
10.
Also, use the new FOLDER property in the ExternalProject
test and in the CMake project itself.
As suggested by Brad, this improves the wording of the error message
in config-mode when config-files were found, but no suitable version.
The patch also contains the small loop-optimization suggested by Brad.

This command allows a user to quickly see the list of all available
test labels. The labels are also printed in verbose show only mode,
alongside their corresponding tests.
Before this patch there were two separate vectors, and the code made sure
they always had the same size.
With this patch the code doesn't have to ensure this anymore, there is only
one vector now.

If in config-mode config files have been found by find_package(), but their
version didn't match the requested version, now all considered files
and their versions are printed (instead of saying "didn't find config file)
Alex
As suggested on cmake-devel, find_package in Config-mode now records
all considered config-files and their versions in
<package>_CONSIDERED_CONFIGS and <package>_CONSIDERED_VERSIONS respectively.
Alex
The proposed solution is to avoid to CopyIfDifferent any links
found in CPACK_INSTALLED_DIRECTORIES but memorize them instead
then at the end of the processing for each dir do re-create the
link in the installed tree.
Current patch should work if the link are "local" to the directory.
When set to OLD, target_link_libraries() silently accepts if it is called
with only one argument and this one argument is not a target.
When set to NEW, this is an error. By default it is a warning now.
Alex
Document explicitly that the first component always exists. Fix the
documentation of SplitPathRootComponent to note that home directory
roots (~/ and ~u/) always have a trailing slash.
The cmGlobalVisualStudio71Generator::WriteProjectDepends method no
longer uses its 'dspname' parameter. Leave off the name to avoid the
unused parameter warning. Later we should refactor the method to avoid
passing the argument altogether.
As discussed on cmake-devel, if target_link_libraries() is called with
only one argument, and this one argument is not a valid target, just
print a warning but don't fail, since otherwise probably some existing
code somewhere might stop building.
Alex
target_link_libraries() did not complain if there was only one argument,
and this one (first) argument wasn't a valid target name, e.g.
add_executable(hello main.cpp)
target_link_libraries(-static-intel)
Here the target "hello" was forgotten in the tll() call, but cmake didn't
complain. With this commit it does.
Alex
Strong dependencies (created by add_dependencies) must be honored when
linearizing a strongly-connected component of the target dependency
graph. The initial graph edges have strong/weak labels and can contain
cycles that do not consist exclusively of strong edges. The final graph
never contains cycles so all edges can be strong.
Utility dependencies are "strong" because they must be enforced to
generate a working build. Link dependencies are "weak" because they can
be broken in the case of a static library cycle.
Commit 438a7e2f (Fix utility dependencies for static libraries in VS
generators, 2007-04-04) implemented utility-only dependencies between
linkable targets by introducing an intermediate non-linkable target.
We convert a dependency of the form
foo -> bar
to the form
foo -> bar_UTILITY -> bar
to prevent foo from including bar on its link line. Previously we added
the extra "_UTILITY" targets explicitly among the project targets before
dependency analysis was performed. Now we generate them separately at
the last moment so that cmGlobalGenerator need not be aware of them.
Compute VS target dependencies in cmGlobalVisualStudioGenerator when the
main global dependency analysis is done. Use these results in each of
the VS generators instead of duplicating the analysis.
find_package() now also stores the required version automatically, so it
can be used by FeatureSummary.cmake.
This was one of the requested features for setting up nightly builds
for KDE, since with this functionality it will be possible to write
a file at the end of each project which lists all required packages
and their versions. This file could then be compared for equality
with an older one and if something has changed the build maintainer
can be emailed.
In FeatureSummary.cmake there is now a new function feature_summary(),
which also allows to print the log to a file or into a variable.
It also allows to specify whether to append to a file or to write a new
one, and what information to log.
Docs are still missing.
Alex
The idea of the patch is to let the install generator define
CPACK_ABSOLUTE_INSTALL_FILES then when CMake is installing
project he will concatenate the list of files and give
it to specific CPack Generator by defining CPACK_ABSOLUTE_INSTALL_FILES
to be the list of ALL files that were installed using absolute destination.
An example of use has been applied to RPM generator which now
tries to automatically build a relocatable package.
When none of the options /Z7, /Zi and /ZI are specified in the cmake
project settings, the project will open in the editor with "Program
Database" as the default debug information format, ending up always
generating PDBs regardless of project configuration.
Modify the output project file so that if the debug information format
is not specified in the cmake project settings it will default to no PDB
generated, just like all the previous other Visual Studio versions.
This problem comes from the fact that Microsoft changed the default
setting of the debug information format to be "Program Database" instead
of "Disabled".
Refactor how cmCTestMemCheckHandler computes the memory tester command
line options to avoid encoding them in a single string just to parse
them again. The EscapeSpaces uses backslahes to escape spaces on UNIX
platforms, so replace other calls to it in CTest that are used to create
human-readable strings with simple double-quoting.

Add platform configuration variable CMAKE_SYSTEM_IGNORE_PATH and user
configuration variable CMAKE_IGNORE_PATH. These specify a set of
directories that will be ignored by all the find commands. Update
FindPackageTest so that several cases will fail without a functioning
CMAKE_IGNORE_PATH.
This is not needed but it does not cost much to do it for all
potentially supported format in libarchive. XZ and LZMA are not
builtin libarchive and require external lib but if
CMAKE_USE_SYSTEM_LIBARCHIVE is ON then we may get it for free.
This will be needed to use cmArchiveWrire in cmCPackArchiveGenerator
with the same feature set as before. Note that adding zip
support to libarchive-wrapper would also makes it easy to add
a new -E zip command to cmake commands.
The multi-argument CompressFiles(...) method has been replace by the
no-argument PackageFiles() method and 3 more member variables. This
will enable implemention of multi-package generators. Now each specific
generator (which overloads PackageFiles()) may decide to change the name
and/or the number of generated package files.
Some stream libraries return size_t from gcount() and some return
ssize_t. Add an explicit cast to ios::streamsize for its return value.
Also refactor use of nnext to reduce the use of casts.

ac26737 Merge branch 'system-libarchive-include' into libarchive-wrapper
3296e6a Include headers from chosen libarchive (#10923)
The libarchive interface accepts size_t but returns ssize_t. The std
streams interface wants streamsize, which is typically ssize_t. Since
no one type for our variable matches without conversions, make the
conversions explicit to avoid -Wsign-conversion and -Wsign-compare
warnings.
Use libarchive through class cmArchiveWrite to implement the method
cmSystemTools::CreateTar. The class includes entries for directories by
automatically traversing the tree on disk.
a7319cf ctest_update: Run 'git submodule' at top level
7bf8dc1 ctest_update: Support ".git file" work trees
65cb72f ctest_update: Abort if Git FETCH_HEAD has no candidates
The git submodule porcelain must be executed from the top level of the
work tree. Use 'git rev-parse --show-cdup' to find the top level
relative to the source tree. This is better than searching up the tree
for .git ourselves because it will always work the same way Git does and
thus honors settings like GIT_DISCOVERY_ACROSS_FILESYSTEM.
Commit c3781efb (Support Git upstream branch rewrites, 2010-06-08)
assumed that ".git/FETCH_HEAD" exists inside the source tree. Fix the
implementation to handle a work tree using a ".git file" to link to its
repository. Use "git rev-parse --git-dir" to locate the real .git dir.
If .git/FETCH_HEAD provides no merge candidate do not attempt to update.
Also log FETCH_HEAD lines as we parse them since they are essentially
output from the git fetch command.

Previously, we were only going into the retry block
for time out conditions. But a "could not connect"
response, or really any sort of curl failure, is
also a condition where we should retry the submit
if the user has requested a retry.
Fix niggly in ExternalProject that would inadvertently
create a log file of output when a command was explicitly
set to the empty string.
Also, increase the default value for showing context
around build errors to 10 lines, up from 6. Also add
the ability to customize this setting so that users
can put it back to 6 or even lower if they want, or
show more if they want.
Clang is smart enough to recognize that "*(int*)0=0" invokes undefined
behavior, warns, and produces an "undefined instruction". The message
in commit "Avoid Clang optimizer bug in testProcess-[45]" (2010-07-02)
is incorrect; this is not a Clang bug. It really is undefined
behavior. Use "*(int*)1=0" to produce a crash instead.
Clang's optimizer, as of clang version 2.8 (trunk 107463), produces the
undefined instruction 'ud2' for the code "*(int*)0=0" on OS X x86_64.
It causes our crash tests to fail because the child process exits with
an invalid instruction instead of a segmentation fault. Work around the
bug by using "*(int*)1=0" in this case.
Add option KWSYS_TEST_BOGUS_FAILURES that can be set by a containing
project or in the CMake cache to list tests known to fail consistently
on a buggy system.
Commit ff1f8d0b (Fix or cast more integer conversions in cmake) changed
a member type from int to size_t. Update the types of variables
compared to these values to be unsigned also.
Both possible result values need to be convertible to the same type.
Some compilers fail to recognize that they can construct std::string
from the empty string literal, so state it explicitly.
Since commit "Provide unix-sytle command line parsing" (2009-07-13) the
reference to KWSYS_C_HAS_PTRDIFF_T in System.c has been meaningless
because the macro was never passed to the compiler!
Separation by ',' only works in VS 2008 and below and does not work in
the PlayStation3 VS plugin. Separation by ';' works in VS 10 and all
prior versions.
Change types of local variables, or casting, or re-arrange
expressions to get rid of "conversion may alter value" warnings
as seen on recent dashboard submissions from londinium.kitware.
I naively assumed in my previous commit that the Convert call
would correctly convert a relative path file name correctly
relative to the makefile's current output directory. It actually
converts it relative to the process's current working directory.
So it would be different depending on how you launched cmake-gui.
This commit ensures that the generated files are always the same
by starting with a full path to begin with, based on the makefile
GetCurrentOutputDirectory method.
Git's diff-tree format has no '\n'-terminated blank line at the end of
its commit message body block if there are no diff lines. Instead the
message body is terminated by '\0' and there is no diff section. Teach
CTest to parse the format in this case.
This is especially important for the Visual Studio 10
generator and its quirky current working directory
behavior.
Also, emit more information about exactly what files are
out of date when cmakeCheckStampFile returns false.
Commit 02f7cfbc (Need to remove the MAKEFLAGS when cmake starts,
2003-05-13) removed the MAKEFLAGS environment variable when CMake starts
to prevent try_compile() from inheriting "make -i". This is unnecessary
in script mode (cmake -P). Instead remove the variable only when
configuring a project.
Tru64's make(1) resolves relative paths in "include" directives with
respect to the includer. This is inconsistent with all other known make
tools. Note that this make tool treats the path literally so we cannot
use our standard FULL path code which escapes spaces. Instead qualify
the paths with $(CMAKE_BINARY_DIR) to avoid the problem.
GCC places the vtable in the object implementing the first non-pure,
non-inline virtual method. Since the symbol is not weak on Tru64, make
the location unique by putting the destructor in a single object file.
The DynamicLoader::LibPrefix and DynamicLoader::LibExtension methods
previously hard-coded the module name components for each platform. Set
them from the CMAKE_SHARED_MODULE_PREFIX and CMAKE_SHARED_MODULE_SUFFIX
CMake variables instead. This ensures consistency in a program that
uses these methods to construct the file names for its own modules.
Use 'git fetch' followed by 'git reset' to update the source tree. This
is better than 'git pull' because it can handle a rewritten upstream
branch and does not leave local modifications. After fetch, parse
FETCH_HEAD to find the merge head that 'git pull' would choose to track
the upstream branch. Then reset to the selected head.
In the normal fast-forward case the behavior remains unchanged.
However, now local modifications and commits will be erased, and
upstream rewrites are handled smoothly. This ensures that the upstream
branch is tested as expected.
Commit 67277bac (Teach ctest_update about Git submodules, 2010-05-04)
accidentally logged "git submodule update" with the prefixes "pull-out"
and "pull-err". Fix it to use "submodule-out" and "submodule-err"
instead.
The CopyFileIfDifferent, CopyFileAlways, CopyAFile and CopyADirectory
methods should always copy permissions. The special cases in which a
caller would pass copyPermissions=false should be handled at the call
site. The parameter needlessly complicates the interface and semantics
of these methods.
If there is a .bat or .cmd file used as a custom command
then the Borland Makefiles generator (specifically) requires
using the "call " syntax before the name of the .bat or .cmd
file. This fix applies to all Makefile based generators where
WindowsShell is true.
On Windows 7 the file size reported by 'stat' on a new file sometimes
reports zero even though the real size is correct. This causes our
CopyFileAlways method to falsely detect copy failure. Work around the
problem by trusting the state of ofstream after writing the file.
Commit 0fafdb7e (Do not copy permissions of files when making the copy
in an install rule, 2008-12-18) added special behavior to KWSys file
copy methods for this special case. Use a local solution to avoid use
of the special behavior so it can be removed later.
Commit 8d0161c8 (Trust umask for file permissions, 2010-01-12) taught
these commands to set permissions to 0666 explicitly. The intention was
to let the open() call inside ofstream handle permsisions so that umask
would be honored. Now we set permissions only when we need to preserve
those on an existing file. New files will be created with umask-based
permissions.
The LINK_FLAGS property is defined only for targets that really link.
These include executables and shared libraries. For static libraries we
define the STATIC_LIBRARY_FLAGS property. Teach the Xcode generator to
make this distinction.
Improve FILE(DOWNLOAD ...):
- Add percent complete progress output to the FILE DOWNLOAD
command. This progress output is off by default to
preserve existing behavior. To turn it on, pass
SHOW_PROGRESS as an argument.
- Add EXPECTED_MD5 argument. Verify that the downloaded
file has the expected md5 sum after download is complete.
- Add documentation for SHOW_PROGRESS and EXPECTED_MD5.
When the destination file exists already and has the
expected md5 sum, then do not bother re-downloading
the file. ("Short circuit" return.)
Also, add a test that checks for the status output
indicating that the short circuit behavior is actually
occurring. Use a binary file for the test so that the
md5 sum is guaranteed to be the same on all platforms
regardless of "shifting text file line ending" issues.
Improve ExternalProject:
- Add argument URL_MD5.
- Add verify step that compares md5 sum of .tar.gz file
before extracting it.
- Add md5 check to download step, too, to prevent
unnecessary downloads.
- Emit a warning message when a file is not verified.
Indicate that the file may be corrupt or that no
checksum was specified.
Only generate .filters files if they are different than the last time
they were generated. This should prevent the unnecessary reloads
being triggered with Visual Studio 2010 builds.
kFreeBSD and Hurd have the same userland as Linux. This change is
necessary to enable kwsysProcessKill() to kill child processes on
kFreeBSD. The bug was detected by CTestTestTimeout test.
Patch from "Modestas Vainius <modestas@vainius.eu>".
See issue #10432.
This is #10466. It didn't crash for me, but also didn't work.
The issue was that a line ending with something else than a # was considered as the
end of the documentation block. If there was simply the end of the file we didn't
get into the correct branch.
Alex
Add the <Email>...</Email> element in Update.xml for each commit
reported. This field was defined by Dart but never really used.
Distributed version control systems use author name and email
instead of a user id, so now it makes sense to use this field.
The expectation of users of the MSVC60, MSVC70, MSVC71, MSVC80, MSVC90
and the new MSVC10 variables is that at most one of them will be set
for any given build tree. This change enforces that expectation for
build trees using Makefile generators. It also fixes the one mismatch
in that expectation to be found in the Visual Studio generator world:
previously, the VS 7.1 generator would set *both* MSVC70 and MSVC71;
now, it only sets MSVC71.
With these changes, user expectations are now met, and the recently
introduced CheckCompilerRelatedVariables test should pass everywhere.
Since commit "Switch to using libarchive from libtar" (2009-10-30) the
the implementation of "tar xz" has printed all paths from the tarball as
a single line with no separator. This fixes the logic to extract
silently as expected.
Git does not automatically checkout the matching version of a submodule
when it checks out a new version of the parent project in the work tree.
If the submodule reference changed in the parent project then we were
reporting the submodule path as a local modification. Work around the
problem in ctest_update using "git submodule update" after "git pull".
For projects with no submodules this is a no-op. See issue #10662.
Also add a submodule to the test project for CTest.UpdateGIT to test the
work-around.
The PDB file name for VCLinkerTool is specified by the xml attribute
"ProgramDatabaseFile", not "ProgramDataBaseFile" (note the lower-case
character 'b'). VS seems to cope with the incorrect capitalization but
the combination of VS 7.1 and Incredibuild does not. See issue #10614.
Report in <UpdateReturnStatus> when the update command line returns
non-zero. Otherwise the failure may be silently ignored since the error
was previously recorded only in the local log file.
These were implementation details of the unused methods
cmMakefile::RegisterData
cmMakefile::LookupData
We simply remove the methods, members, and class cmData.
For builds from Git repositories, add "-g<commit>" to the end of the
version number. If the source tree is modified, append "-dirty".
For builds from CVS checkouts, add "-cvs-<branch>".
Add the [.tweak] version component throughout the policy implementation.
Document all components for the cmake_policy(VERSION) command. Record
the tweak level in which each policy was introduced (0 for all current
policies). In generated documentation we report the tweak level only if
it is not zero. This preserves existing documentation.
The command now accepts four version components in the format
major[.minor[.patch[.tweak]]]
This corresponds to the new versioning scheme introduced recently.
Prepare to switch to the workflow described by "git help workflows". In
this workflow, the "master" branch is always used to integrate topics
ready for release. Brand new work merges into a "next" branch instead.
We need a new versioning scheme to work this way because the version on
"master" must always increase.
We no longer use an even/odd minor number to distinguish releases from
development versions. Since we still support cvs checkout of our source
tree we cannot depend on "git describe" to compute a version number
based on the history graph. We can use the CCYYMMDD nightly date stamp
to get a monotonically increasing version component.
The new version format is "major.minor.patch.(tweak|date)". Releases
use a tweak level in the half-open range [0,20000000), which is smaller
than any current or future date. For tweak=0 we do not show the tweak
component, leaving the format "major.minor.patch" for most releases.
Development versions use date=CCYYMMDD for the tweak level. The
major.minor.patch part of development versions on "master" always
matches the most recent release.
For example, a first-parent traversal of "master" might see
v2.8.1 2.8.1.20100422 v2.8.2
| | |
----o----o----o----o----o----o----o----o----
Since the date appears in the tweak component, the next release can
increment the patch level (or any more significant component) to be
greater than any version leading to it. Topic branches not ready for
release are published only on "next" so we know that all versions on
master lead between two releases.
Commit "Support more special characters in file(STRINGS)" (2009-10-06)
attempted to support parsing strings from binaries produced by the
Portland Group Fortran compiler. The compiler seems to put an extra
byte just at the end of its string literals. Previously we dealt with
this by explicitly enumerating bytes known to occur, but it seems that
many such possibilities exist. Now we support extraction of strings
that end in any non-ASCII character.
The SaveRestoreEnvironment helper object makes sure that the
original environment is restored immediately after the
StartProcess call returns rather than waiting for the end
of the test. When tests are executed in parallel, there is
no guarantee about the ordering of EndTest calls relative
to StartTest calls. In fact, it would be odd for them to
be nested nicely. Therefore, to avoid the corruption of
the calling ctest's environment, the original environment
must be restored before ForkProcess returns.
Detect the runtime linker's search path and add to the compile time
linker's search path. This is needed because OpenBSD's static linker
does not search for shared library dependencies in the same places as
the runtime linker.
Teach kwsysProcessKill to identify processes on this platform using the "ps"
command just as on Linux. Patch from Modestas Vainius <modax@debian.org>.
See issue #10432.
The compiler id is checked for C++ and C, if there is not one
of those available, then just default to gcc. This makes it
work with Fortran, or None projects.
This makes the behavior of the build with the Visual Studio generators
equivalent to the behavior of makefile based builds. After an error
in a custom command sequence, the build stops and reports an error
rather than executing the remaining commands in the sequence.
Create platform variable "CMAKE_<LANG>_RESPONSE_FILE_LINK_FLAG" to
specify an alternative to "@" for referencing response files. It
applies specifically to response files with linker options.
See issue #10401.
Response files are parsed by tools, not by shells. We teach
cmLocalGenerator::Convert() a new "RESPONSE" output format and use it
for objects listed in response files. It does not do special slash or
MSYS root translation like the "SHELL" format does. This is necessary
for GNU tools on Windows to understand response file content.
See issue #10401.
Allow the user to set the CMake variable CTEST_COST_DATA_FILE, which will be used to store the cost data from test runs. If not set, defaults to the original location in the build tree Testing/Temporary dir.
Ensure that the HTML documentation generated by CMake complies with
"XHTML 1.0 Strict":
- All tags are properly closed and DOCTYPE is specified
- Useful for downstream XML-processors (e.g. for extracting section
titles)

Now instead of one linked resource for each project() just one linked
resource to the top level source directory is created.
This should really avoid this type of name clashes. And to me it looks also
much less confusing.
Hopefully the name "[Source directory]" containing a space and square
brackets doesn't lead to problems somewhere. Here it works.

In commit 'Create KWSYS_PLATFORM_INFO_TEST macro' (2009-11-20) we
implemented the macro to use a cache entry to avoid re-running the
try_compile(). However, the output copied from the try_compile is
needed on every configure. If the user wipes out the build tree but not
the cache file then the try_compile() will not re-run to recreate the
needed file. We address the problem by teaching the macro to run the
try_compile() whenever its output file does not exist.
We store custom command rule hashes in CMakeFiles/CMakeRuleHashes.txt
persistently across CMake runs. When the rule hash changes we delete
the custom command output file and write a new hash into the persistence
file.
This functionality was first added by the commit 'Introduce "rule
hashes" to help rebuild files when rules change.' (2008-06-02).
However, the implementation in cmGlobalGenerator::CheckRuleHashes kept
the file open for read when attempting to rewrite a new file. On
Windows filesystems this prevented the new version of the file from
being written! This caused the first set of rule hashes to be used
forever within a build tree, meaning that all custom commands whose
rules changed would be rebuilt every time CMake regenerated the build
tree.
In this commit we address the problem by splitting the read and write
operations into separate methods. This ensures that the input stream is
closed before the output stream opens the file.
We use 'git diff-index' to detect local modifications after pull. On
some filesystems the work tree timestamps of a few files may be dated
after the index, making them appear as locally modified. We address the
problem by using 'git update-index --refresh' to refresh the index and
avoid false local modifications.
Our internal path processing methods assume no trailing slashes, but bzr
adds trailing slashes to updated directories. This can lead to empty
entries in Update.xml files. We address the problem by stripping the
slashes as soon as they are parsed.
Cygwin versions .dll files by putting the version number in the file
name. Our fix to issue #3571 taught CMake to do this, but it used the
VERSION target property. It is better to use the SOVERSION property
since that is the interface (rather than implementation) version.
Change based on patch from issue #10122.
When building on Cygwin without -mwin32, the _WIN32 macro may not be
defined. SharedForward must still set the PATH environment variable to
ensure runtime dependencies are found.
The 'ldd' wrapping feature uses 'cygcheck' for now since a real ldd tool
is not available in Cygwin 1.5. We can change to use the real ldd when
we choose to stop supporting legacy Cygwin and require 1.7.
When kwsys is built using GCC visibility support can be used. This is similar
to the way that Windows exports symbols in DLLs, and requires projects that
build kwsys to change the default visibility using some compiler flags. See
http://gcc.gnu.org/wiki/Visibility for more details about GCC visibility.
Makefile dependencies must be escaped using cmLocalGenerator::Convert
with the cmLocalGenerator::MAKEFILE option. This fixes Fortran module
dependencies with spaces in the path. We test the fix by adding a space
to one of the module paths in the Fortran test.
The improved text gives very clear information when either the CMakeLists.txt or CTestConfig.cmake file is missing. Hopefully, it makes it easier for those poor future souls who encounter these messages to solve their problems quickly.
If APPEND is given to ctest_start, it will read the tag from the current existing Testing/TAG file rather than creating a new one based on the current time stamp. This allows a developer to run several dashboard scripts in a row, all of which will share the same tag/stamp/buildid when they finally get submitted to CDash. Now you can split the running of build phases and test phases for the same dashboard row into multiple scripts.
Before this commit, the value of PATH at cmake time was put into the eclipse
project file. The problem with this is that this will be lost the first time
cmake is rerun from an build inside eclipse which was started without the
environment externally already set.
This patch now:
-adds the env.var to the cache if it is not already in the cache
-reuses the variable from the cache if it is in the cache, but not in the env.
-uses the variable from the cache if it contains the whole content of the
current env.var (e.g. if it is the full PATH plus the MSVC dirs)
Also store INTEL_LICENSE_FILE in the project file if an Intel compiler is used.

The Eclipse and KDevelop generators set the VERBOSE environment variable to
TRUE in the project files, because they must be able to "see" the full
command lines and errors, otherwise they can't parse the errors. But the
VERBOSE env.var. also enables cmakes own verbose output, which can be quite
long. This commit introduces an environment variable CMAKE_NO_VERBOSE, which
when set disables cmake's verbose output also when VERBOSE is set. This
env.var is now set by both the Eclipse and the KDevelop generators.

Previously we produced commit times formatted like
1261403774 -0500
which is what the Git plumbing prints. Now we use a human-readable
format like
2009-12-21 15:28:06 -0500
which is still easy to machine-parse.
