Expose GLSLANG__TESTS and GLSLANG_ENABLE_INSTALL as options
that can be controlled from an enclosing project, or from the
command line.
They retain the prior default behaviour. In particular, if Glslang
is not the top level project, then they default to OFF.
Fixes: #3507
XCode 15 includes a completely new linker implementation.
Hence some flags are deprecated.
The default is now error so we can simply remove the linker option.
This makes it more clear to users when SPIR-V optimization is disabled
because SPIRV-Tools could not be found, and suggests alternatives for
finding it.
This allows to build with optimizer enabled, if external SPIR-V tools
libraries are available in the system. It is quite common in *nix world
to package spirv-tools and glslang separately.

Build fails due to external dependency on SPIRV-Tools.
EX:
```
-- Looking for pthread_create in pthread
-- Looking for pthread_create in pthread - found
-- Found Threads: TRUE
CMake Error at External/spirv-tools/CMakeLists.txt:15 (cmake_minimum_required):
CMake 3.17.2 or higher is required. You are running version 3.14.0
```
The web/emscripten build has been broken for an unknown amount of time
and for multiple reasons:
- Calling `cat` on Windows
- The latest version of wasm-ld does not support the `--no-undefined`
flag
- `ccall` was not being exported
Fixes#3272.
Currently with the build instructions provided in README.md
the build will fail.
In the r25 NDK the CMake toolchain defaults to the legacy path,
due to a bug in the current implementation.

The FindPythonInterp and FindPythonLibs modules, which have
been deprecated since CMake 3.12, have been removed by policy
CMP0148. Port projects to FindPython3, FindPython2, or FindPython.
While trying to set a default for CMAKE_INSTALL_PREFIX sounds
appealing it has multiple issues.
It's particularly problematic for open source projects where
many users try to accomplish many different things.
It's also conflicting with the new way of installing with cmake
IE: `cmake --install build --prefix build/install`
I've already removed similar logic in various other Khronos
repositories a while ago to address similar complaints.
closes#1015
This is no longer needed with modern CMake.
I've already removed this from several Khronos repos.
See this stackoverflow for modern approaches to setting ccache via cmake:

OpenBSD does not link shared libs against libc so it is expected
that the use of --no-undefined when linking will fail.
Also garbage collect CMAKE_VERSION check while here, as requested, since
the minimum version is already 3.14.
At least on openSUSE, the usual installation location for cmake support
files is ${MAKE_INSTALL_LIBDIR}/cmake/<name>
$ find /usr/lib64 -name '*.cmake' | grep /cmake/ | wc -l
834
$ find /usr/lib64 -name '*.cmake' | grep -v /cmake/ | wc -l
8
which is also used by glslang with these changes.
pre compiled headers leads to "internal error in mingw32_gt_pch_use_address, at config/i386/host-mingw32.c:192: MapViewOfFileEx: Attempt to access invalid address"
