All commands accepting file paths should normalize the slashes so that
the string-represented names can be compared reliably. The commands
add_library and add_executable have done this for years. We taught
add_custom_command to normalize its OUTPUT names in commit a75a0a14
(Normalize add_custom_command OUTPUT names, 2010-12-15). We handled a
special case of the DEPENDS option in commit 7befc007 (Handle trailing
slashes on add_custom_command DEPENDS, 2011-01-26).
Teach both add_custom_command and add_custom_target to normalize slashes
of DEPENDS files up front. This approach subsumes the above-mentioned
special case so remove the one line added for it but keep its test.
Extend the CustomCommand test to check that slash count mismatches
between custom command OUTPUT and DEPENDS can still be linked correctly.

6e8a67f Generate target-wide flags before individual build rules
d099546 Factor old-style -D flags out from -I flag generation
Create platform option CMAKE_<lang>_USE_RESPONSE_FILE_FOR_INCLUDES to
enable use of response files for passing the list of include directories
to compiler command lines.
Move the GetDefineFlags call from cmLocalGenerator::GetIncludeFlags to
all call sites so that the method exclusively constructs a string of
include search path flags.
The cmCustomCommandGenerator::GetCommand method completely replaces the
purpose of this method. Re-implement GetRealLocation inline at the only
remaining call site and remove it.
A custom command may name a target created by add_custom_target in its
DEPENDS field. Treat this case as a target-level dependency only since
a custom target provides no standard file on which to add a file-level
dependency.
Factor out reading of CMAKE_CONFIGURATION_TYPES and CMAKE_BUILD_TYPE
into cmMakefile::GetConfigurations. Read the former only in
multi-config generators.
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.
The Watcom tools do their own command-line parsing and do not accept
double-quotes. Instead we single-quote the target output name when
invoking wlink and other Watcom tools. This fixes support for spaces in
the target output directory path when it is not under the build tree.
The CMAKE_OSX_ARCHITECTURES variable works only as a global setting.
This commit defines target properties
OSX_ARCHITECTURES
OSX_ARCHITECTURES_<CONFIG>
to specify OS X architectures on a per-target and per-configuration
basis. See issue #8725.
This commit re-writes Borland compiler build rules. We split the rules
into modern <os>-<id>-<lang> information modules but share a common
macro between languages to avoid duplication.
We also address a bug in the previous rules that would build some target
types against the static Borland runtime and others against the shared
Borland runtime in one build tree. Now we always use the shared runtime
as is the default in the rules for MS tools.
This creates cmTarget::GetFeature and cmMakefile::GetFeature methods to
query "build feature" properties. These methods handle local-to-global
scope and per-configuration property lookup. Specific build features
will be defined later.
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.
In cmLocalGenerator::ConvertToRelativePath we normally convert to
relative path only if the local and remote paths both lie inside the
source tree or both lie inside the build tree. This commit adds an
optional 'force' argument to allow conversion even when this rule is
violated.
Previously we checked for this flag by parsing the version number of GCC
out of 'gcc --version', but this is not reliable because the format can
vary greatly. Now we run 'gcc -v --help' and look for '-isysroot' in
the list of options.
We also now store the result on a per-language basis in the per-compiler
info file "CMake<LANG>Compiler.cmake". This is necessary to make it
accessible from try-compile projects so that they generate correctly.
Until now CMake accidentally accepted add_subdirectory() and subdirs()
calls referring to directories that do not contain a CMakeLists.txt
file. We introduce CMake Policy CMP0014 to make this case an error.
This method tells the cmMakefile to read the input CMakeLists.txt file.
We factor out the call into a ReadInputFile method so it can be extended
without polluting the Configure method.
Much of the code in this method was dedicated to computing ObjectMaxPath
after configuring the directory. We move this last step into its own
ComputeObjectMaxPath method for better organization.
The cmLocalGenerator::Configure method sets its cmLocalGenerator
instance as the global generator's current local generator during
configuration. This commit refactors management of the current local
generator to use an automatic variable. This will allow early returns
from the method.
This method previously required the global generator to be passed, but
that was left from before cmTarget had its Makefile member. Now the
global generator can be retrieved automatically, so we can drop the
method argument.
Previously we rejected all preprocessor definition values containing
spaces for the VS6 IDE generator. In fact VS6 does support spaces but
not in combination with '"', '$', or ';', and only if we use the sytnax
'-DNAME="value with spaces"' instead of '-D"NAME=value with spaces"'.
Now we support all definition values that do not have one of these
invalid pairs. See issue #8779.
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).
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.
This fixes CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES to be used for all
generators instead of just those that construct their own compiler
command lines directly. See issue #8598.
It does not make sense to call the reverse Convert signature (for remote
paths corresponding to CMake-managed directories) with NONE or FULL
since they have no path. Patch from Modestas Vainius. See issue #7779.
This creates variable CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES to
specify implicit include directories on a per-language basis. This
replaces the previous platform-wide variable. It is necessary to
avoid explicit specification of -I/usr/include on some compilers
(such as HP aCC) because:
1.) It may break ordering among system include directories defined
internally by the compiler, thus getting wrong system headers.
2.) It tells the compiler to treat the system include directory
as a user include directory, enabling warnings in the headers.
See issue #8598.
We used to suppress generation of -I/usr/include (and on OSX also
-I/usr/local/include). This behavior seems to cause more trouble than
it's worth, so I'm removing it until someone encounters the original
problem it fixed. See issue #8598.
This defines global, directory, and target properties
RULE_LAUNCH_COMPILE, RULE_LAUNCH_LINK, and RULE_LAUNCH_CUSTOM. Their
values specify 'launcher' command lines which are prefixed to compile,
link, and custom build rules by Makefile generators.
The old install_files, install_programs, and install_targets commands
used to permit installation to the top of the prefix by specifying
destination '/'. This was broken in 2.6.0 to 2.6.2 by changes to
enforce valid destinations that did not account for this case. This
change fixes the case by converting the install destination to '.' which
is the new-style way to specify the top of the installation prefix.
