Chuck Atkins 1abd7cd930 Use containers of labeled search paths instead of individual members
Manage classes of search paths in labeled containers.  This removes the
need to have a seperate member variable for each type of search path, but
also allows path types to be grouped togethor in various different ways
and manipulated as subsets of the full set of search paths.

Chuck Atkins 2a9ac4bd83 Encapsulate search path manipulation functions into a seperate class.
The functions for adding the various different types of paths have been
factored out into a new class, cmSearchPath.  It is to be used as a helper
container class for the various find_* commands.

Chuck Atkins 32922840e7 Refactor and seperate search path construction for find commands
Prior to this commit, the set of search paths to traverse for find commands
was incrementally constructed.  This change allows each group of paths, i.e.
CMakeVariablePaths, UserHintsPaths, SystemEnvironmentPaths, etc. to be
constructed and manipulated independently, and then all combined togethor.

Nils Gladitz cc1139cc30 strings: Remove redundant calls to std::string::c_str()
Replacements were detected and performed by the clang tool
remove-cstr-calls on a linux build.

Stephen Kelly 21c573f682 Remove some c_str() calls.
Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.

Ben Boeckel 3742bb0d32 stringapi: Use strings for variable names
Variable names are always generated by CMake and should never be NULL.

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 7cd65c97fa Add CMAKE_SYSROOT variable to set --sysroot when cross compiling.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.

The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.

Brad King 13aea6d175 cmFindCommon: Revert accidental change
In commit c4373b33 (cmTarget: Make GetProperty() const, 2013-10-29)
we accidentally changed the cmFindCommon.cxx logic in a way that
looks like a local experiment leftover that went unnoticed due to
the size of the other changes in the commit.  Revert it.

Stephen Kelly c4373b33b2 cmTarget: Make GetProperty() const.
This has follow-on effects for other methods and classes. Further
work on making the use of const cmTarget pointers common can be
done, particularly with a view to generate-time methods.

Stephen Kelly 0416c94f64 Revert "Use --sysroot when cross compiling."
This reverts commit de4da665d3.

This feature is not yet ready for release. It needs to be
merged with the CMAKE_OSX_SYSROOT feature.

Brad King b0cd630521 Refactor find_* command final path list computation
All find_* commands re-root the list of paths and then add trailing
slashes.  Factor this pair of calls out into a dedicated method.  The
new method would be the only caller to AddTrailingSlashes, so subsume
that method into it.

Brad King 5303fbf09e Speedup find_* commands (#11412)
Delay computation of the command documentation until it is needed.
It is wasteful to do it in the constructor on every call.

Todd Gamblin 1221581aa8 Teach find_* commands to ignore some paths
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.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
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.

Brad King 5b406c9044 ENH: Add HINTS option to find_* commands.
- Hints are searched after user locations but before system locations

Brad King 789c167b6f ENH: Refactor cmFindCommon, cmFindBase, and cmFindPackageCommand
- Add each part of the search order in a separate method.
  - Collect added paths in an ivar in cmFindCommon.

    - Enables 32-/64-bit registry view for find_package
    - Disables registry expansion for paths not specified
      with the PATHS argument, which is not expected.
