* Add "ICU_" suffix to all _FOUND variables
* Ensure cache variables can also be used with correct
ICU_ suffix and compatibility name
* Improve ICU_DEBUG messages to verify compatibility and
corrected variable names are set to the correct values
CMP0074 causes FindICU.cmake to always prefer the 32-bit version of ICU
programs/libraries on Windows. NO_PACKAGE_ROOT_PATH reverts this behavior.
Fixes: #18742
The files Makefile.inc and pkgdata.inc are installed by ICU to
<libdir>/icu and on some distributions to <libdir>/<arch>/icu.
These are required by ICU tools like pkgdata, and so are needed
by other package build systems at build time, in addition to the
libraries and executables already searched for.
Search for the files and create cache entries for them, as done
for executables.
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names and years are hard to maintain and often out-of-date or plain wrong.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.
