In `cmState::GetGlobalProperty` we use a macro to produce a string of
the form ";a;b;c" and want to return "a;b;c" by skipping the leading
";". Switch from pointer arithmetic to indexing+addressing to silence
the "warning: adding 'int' to a string does not append to the string"
diagnostic from Clang.

-- Forward GHS platform variables to try_compile()
CMAKE_TRY_COMPILE_PLATFORM_VARIABLES only worked for source signature try_compile()
-- Update tests to no longer add GHS platform variables to try_compile()
-- Avoid linker error in GhsMulti/GhsMultiCompilerOptions/CMakeLists.txt by building library
Since commit v3.10.0-rc1~391^2~3 (Add directory property 'LABELS' and
CMAKE_DIRECTORY_LABELS variable, 2017-06-23) this command was
accidentally not allowed in script mode. It was dropped because
`ctest -S` mode needs to start with CMake's normal script mode and
then replace the `set_directory_properties` implementation. Restore
the normal `set_directory_properties` in script mode and then add
special logic to replace it in ctest. Also add a test case.
Fixes: #18523
These new capabilities enable to manage link directories
Two new properties:
* target properties: LINK_DIRECTORIES and INTERFACE_LINK_DIRECTORIES
One new command
* target_link_directories(): to populate target properties
Fixes: #17215
This family enable to manage link flags
Three new properties:
* directory property: LINK_OPTIONS
* target properties: LINK_OPTIONS and INTERFACE_LINK_OPTIONS
Two new commands
* add_link_options(): to populate directory property
* target_link_options(): to populate target properties
Fixes: #16543
Store both the as-written and lower-case command names and use
the latter to avoid case-insensitive string comparisons.
With this I obtain 2-6% speed increase (on Windows) for the configure
step with no significant changes in memory usage. A case-insensitive
comparison is a lot slower than just calling `==` because the operator
will use things like memcmp, so prefer the latter.
The `cmSystemTools::LowerCase` function allocates a new string each time
it is called, so before this change we were allocating in:
* cmMakefile::Configure two times for each function
(to look for `cmake_minimum_required` and `project`)
* cmMakefile::ExecuteCommand twice by function by calling
cmState::GetCommand and copying the name
Now we are only allocating once by function instead of four.
* Change some functions to take `std::string` instead of
`const char*` in the following classes: `cmMakeFile`, `cmake`,
`cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator`
and a few others.
* Greatly reduce using of `const char*` overloads for
`cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`.
* Remove many redundant `c_str()` conversions throughout the code.
Port dependents to the new locations as needed.
Leave behind a cmState.h include in cmListFileCache to reduce noise. It
is removed in a following commit.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
Add SOURCE_DIR and BINARY_DIR directory properties that return the
absolute paths to the corresponding directories. These correspond
to the target properties of the same names that we already have.
