Stephen Kelly 7521da2852 Introduce CMAKE_STAGING_PREFIX variable.
This variable can be useful in cross-compiling contexts where the
sysroot is read-only or where the sysroot should otherwise remain
pristine.

If the new CMAKE_STAGING_PREFIX variable is set, it is used instead
of CMAKE_INSTALL_PREFIX when generating the installation rules in
cmake_install.cmake.

This way, the CMAKE_INSTALL_PREFIX variable
always refers to the installation prefix on the target device, regardless
of whether host==target.

If any -rpath paths passed to the linker contain the CMAKE_STAGING_PREFIX,
the matching path fragments are replaced with the CMAKE_INSTALL_PREFIX.
Matching paths in the -rpath-link are not transformed.

The cross-prefix usr-move workaround is assumed not to require extension
regarding CMAKE_STAGING_PREFIX. The staging area is a single prefix, so
there is no scope for cross-prefix symlinks. The CMAKE_INSTALL_PREFIX
is still used to determine the workaround path, and that variable
remains the relevant one even if CMAKE_STAGING_PREFIX is used. If the
generated export files are deployed to the target, the workaround
will still be in place, and still be employed if required.

Stephen Kelly fe057ab3cd Allow disabling adding the install prefix to the prefix search path.
In certain scenarios, it is preferable to keep a 'dirty' install prefix
than to clear it, and to expect that content will not be found there.
Add a CMAKE_FIND_NO_INSTALL_PREFIX variable that can be set to disable
searching the install prefix.

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

Run the following shell code:

git ls-files -z -- \
 bootstrap doxygen.config '*.readme' \
 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \

Brad King eae45a67e7 Search MacPorts /opt/local prefix on Mac
Include this prefix in CMAKE_SYSTEM_PREFIX_PATH so that it will be used
for all find* commands.  Previously only find_library and find_path
would look under /opt/local/lib and /opt/local/include, respectively.

Brad King 12dcf9e4fb Search prefix /usr before root prefix /
Commit "Find locally installed software first" made /usr/local the first
prefix searched to be consistent with the Filesystem Hierarchy Standard:

  http://www.pathname.com/fhs/

The standard also implies that the root prefix "/" should not have any
package or development files.  The "/bin" and "/lib" directories should
have only minimal contents to boot the system.  No "/include" ever
exists.  This commit re-orders the search path prefix list from

  /usr/local
  /
  /usr

to

  /usr/local
  /usr
  /

to prefer package and development files over low-level system files.
See issue #10136.

On Cygwin /usr/lib == /lib and /usr/bin == /bin.  This change also makes
search results report locations as "/usr/..." instead of "/lib/...".
See issue #10122.

Brad King f98a4e63fd Avoid (Unix|Windows)Paths.cmake multiple include
Block multiple inclusion because "Modules/CMakeCInformation.cmake"
includes "Platform/${CMAKE_SYSTEM_NAME}" even though the generic
module "CMakeSystemSpecificInformation.cmake" already included it.

The extra inclusion is a work-around to address issue #4772 without
intrusive platform file changes.  Once those changes are made the
work-around and these include blockers can be removed.  See issue #9656.

Brad King c118fd4c55 Find locally installed software first
This commit re-orders the search path prefix list from

  /
  /usr
  /usr/local

to

  /usr/local
  /
  /usr

so that locally-installed software is preferred.

This makes the search consistent with the Filesystem Hierarchy Standard:

  http://www.pathname.com/fhs/

See issue #9657.

Brad King cb788e8f6d ENH: Re-enable system include dir suppression
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.

Alexander Neundorf 176fe63d15 ENH: UNIX, CYGWIN, WIN32, APPLE, QNXNTO and BEOS are not longer set in
cmMakefile.cxx, but now in the platform files and are now valid for the
target platform, not the host platform.
New variables CMAKE_HOST_WIN32, CMAKE_HOST_UNIX, CMAKE_HOST_APPLE and
CMAKE_HOST_CYGWIN have been added in cmMakefile.cxx (...and have now to be
used in all cmake files which are executed before
CMakeSystemSpecificInformation.cmake is loaded). For compatibility the old
set is set to the new one in CMakeDetermineSystem.cmake and reset before the
system platform files are loaded, so custom language or compiler modules
which use these should still work.
