We set CMAKE_PREFIX_PATH from the --prefix= option. The calling shell
might not translate "/c/..." to "c:/..." paths but we need to store
Windows paths in CMake cache variables. Pass the specified path through
the MSYS shell in a form it will convert to a Windows path using the
MSYS fstab.
Some MSYS bash implementations leave trailing space on the command line
to 'cmd /c echo ...' after quoting the message. The Windows echo tool
preserves both the quotes and the trailing space. Use a sed expression
that strips quotes and trailing spaces after the end quote.
Provide an interface simpler than --init= to set cache values during
bootstrap builds. For example:
./bootstrap --system-zlib -- -DZLIB_ROOT=/opt/zlib
will configure CMake with a system zlib library and initialize ZLIB_ROOT
in the cache for use by FindZLIB.
This adds the ability for packagers to specify that some libraries
should use system versions and others should use the CMake versions.
This allows a bit of flexibility and means Homebrew (an OSX package
manager) no longer has to continue to patch the CMake build process.

The Makefile, VS, and Xcode generators previously duplicated some custom
command line generation code. Factor this out into a separate class
cmCustomCommandGenerator shared by all generators.
Look for a C/C++ compiler pair from known toolchains on some platforms.
This makes it less likely that mismatched compilers will be found.
Check only if the environment variables CC and CXX are both empty.
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.
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.
Since Haiku does not have /usr (and therefore /usr/local), this commit
changes the default install prefix to the equivalent directory of
/boot/common.
See issue #9607.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
We need to do this KWSys configuration test in the CMake bootstrap
script to create a proper cmsys/Configure.hxx file. This fixes the
bootstrap script which was broken by the addition of the test to KWSys.
This introduces a new syntax called "generator expressions" to the test
COMMAND option of the add_test(NAME) command mode. These expressions
have a syntax like $<TARGET_FILE:mytarget> and are evaluated during
build system generation. This syntax allows per-configuration target
output files to be referenced in test commands and arguments.
Previously each new variable scope (subdirectory or function call) in
the CMake language created a complete copy of the key->value definition
map. This avoids the copy using transitive lookups up the scope stack.
Results of queries answered by parents are stored locally to maintain
locality of reference.
The class cmDefinitions replaces cmMakefile::DefinitionsMap, and is
aware of its enclosing scope. Each scope stores only the definitions
set (or unset!) inside it relative to the enclosing scope.
The Debian Almquist Shell (dash) provides minimal POSIX compliance
instead of the power of bash. It converts literal '\n' to a real
newline even in a single-quoted string. This works around the problem
by avoiding the literal. We can no longer use HEREDOC.
A few sweeping changes were needed:
- Avoid use of HEREDOC, which does not seem to work.
- Avoid extra '.' in paths by using '_cmk' and '_tmp'
instead of '.cmk' and '.tmp'.
The Compaq compiler (on VMS) includes 'String.c' in source files that
use the stl string while looking for template definitions. This was the
true cause of double-inclusion of the 'kwsysPrivate.h' header. We work
around the problem by conditionally compiling the entire source file on
a condition only true when really building the source.
This enables the --enable-auto-import linker flag on Cygwin when linking
executables. It works with the old gcc 3.x compiler and is necessary
for the new gcc 4.x compiler. See issue #9071.
This moves code which generates ADD_TEST and SET_TESTS_PROPERTIES calls
into CTestTestfile.cmake files out of cmLocalGenerator and into a
cmTestGenerator class. This will allow more advanced generation without
cluttering cmLocalGenerator. The cmTestGenerator class derives from
cmScriptGenerator to get support for per-configuration script
generation (not yet enabled).
A new cmScriptGenerator base class factors out the non-install-specific
part of cmInstallGenerator. This will be useful for other generators
that want per-configuration functionality.
This moves the version numbers into an isolated configured header so
that not all of CMake needs to rebuild when the version changes.
Previously we had spaces, dashes and/or the word 'patch' randomly chosen
before the patch number. Now we always report version numbers in the
traditional format "<major>.<minor>.<patch>[-rc<rc>]".
We still use odd minor numbers for development versions. Now we also
use the CCYYMMDD date as the patch number of development versions, thus
allowing tests for exact CMake versions.

CMake-SourceFile2-bp and CMake-SourceFile2-b-mp1 to trunk. This
commit is surrounded by tags CMake-SourceFile2-b-mp1-pre and
CMake-SourceFile2-b-mp1-post on the trunk.
The changes re-implement cmSourceFile and the use of it to allow
instances to be created much earlier. The use of cmSourceFileLocation
allows locating a source file referenced by a user to be much simpler
and more robust. The two SetName methods are no longer needed so some
duplicate code has been removed. The strange "SourceName" stuff is
gone. Code that created cmSourceFile instances on the stack and then
sent them to cmMakefile::AddSource has been simplified and converted
to getting cmSourceFile instances from cmMakefile. The CPluginAPI has
preserved the old API through a compatibility interface.
Source lists are gone. Targets now get real instances of cmSourceFile
right away instead of storing a list of strings until the final pass.
TraceVSDependencies has been re-written to avoid the use of
SourceName. It is now called TraceDependencies since it is not just
for VS. It is now implemented with a helper object which makes the
code simpler.
