The hash_fun.hxx header is configured whether FundamentalType is enabled
or not and so cannot depend on it. Run the relevant platform tests
whether or not FundamentalType is on and configure the result directly
into hash_fun. While at it, remove the dependence of SystemInformation
on FundamentalType too since it needs only information that we now
always compute.

Teach the Plugin test to check that the NO_SONAME target property works
as documented. Check that the IMPORTED targets are written with the
correct properties. When readelf is available use it to check the
actual binary files for SONAME fields.
Add a boolean target property NO_SONAME which may be used to disable
soname for the specified shared library or module even if the platform
supports it. This property should be useful for private shared
libraries or various plugins which live in private directories and have
not been designed to be found or loaded globally.
Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
definition as long as soname supports is enabled for the target in
question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
rules in case third party projects still use it. Such projects would
not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since
-install_name is soname on OS X, this should not be a problem if this
variable is expanded only if soname is enabled.
The Ninja generator performs rule variable substitution only once
globally per rule to put its own placeholders. Final substitution is
performed by ninja at build time. Therefore we cannot conditionally
replace the soname placeholders on a per-target basis. Rather than
omitting $SONAME from rules.ninja, simply do not write its contents for
targets which have NO_SONAME. Since 3 variables are affected by
NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if
soname is enabled.
By tracking a stamp file within the git clone script itself.
Avoids a 2nd git clone operation after switching from Debug
to Release builds in Visual Studio, or vice-versa.
Add "private/internal-use-only" function _ep_get_step_stampfile
to get the name of the stamp file for a given step.
The functionality provided by this commit should be identical
to its parent commit.
Since commit ed0075bd (Use relative paths for custom command inputs,
2011-06-22) CMake generates full paths to source files in VS 10 project
files to avoid trouble with deep source/build tree paths. However, the VS
10 IDE will not populate the source file property dialog for a file
referenced by full path. Instead use a relative path when possible. When
not possible produce a detailed warning explaining the problem and
suggesting use of shorter directory paths.
CMake <= 2.8.4 generated VS 10 project files with a relative path to
source files. Then commit ed0075bd (Use relative paths for custom command
inputs, 2011-06-22) switched to using relative paths only for source files
holding custom commands and full paths for other sources. This behavior
was inhereted by the VS 11 generator but is not needed so use the
workaround only for exactly VS 10. Explain the behavior in comments.
Most CMake generators produce relative paths within the build tree and
full paths to files outside the build tree. Make VS 10 and VS 11
project files consistent with this approach except for paths forced to
be relative to work around a VS 10 bug.
Remove the duplicate source file classification logic used to generate
the filter files. Instead record during the main vcxproj file
generation the source files generated for each tool. Also record
whether or not each source file is converted to a relative path. Use
the recorded result during filter generation to ensure consistency
between the project file and filter file.
The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory. However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv. If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.
Replace use of putenv with setenv/unsetenv when available. The latter
manage internal copies of the values passed instead of referencing the
original memory. When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory. This requires an "unputenv" implementation. On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms. On other platforms fall back to direct
manipulation of "environ".
Also add UnPutEnv to the API and add a test for the behavior of both.
