this controls the config.h define of the same name and matches the
behavior of configure's --disable-threading

Also fix the variables: we need to check for PTHREAD_PRIO_INHERIT
and PTHREAD_CREATE_JOINABLE (not PTHREAD_CREATE_UNDETACHED) and
internally use HAVE_PTHREAD_PRIO_INHERIT and PTHREAD_CREATE_JOINABLE
(and not HAVE_PTHREAD_CREATE_JOINABLE).
cmake/config.h.in actually had the right variables.

Since
a376e7b9 Fix compilation on windows and clang-cl+ninja.
the highest level assembly flag (/arch:AVX / -msse4.1) would be applied
to all assembly files. This could result in higher level instructions
being used which would defeat the runtime cpu detection check and could
result in a crash.
With this change -m style flags are used with clang-cl as it supports
them and allows the correct level to be set. With at least Visual
Studio 12 (2013)+ /arch is not necessary to build SSE2 or SSE4 code
unless a lesser /arch is forced so these flags are avoided. This matches
the nmake build.
For emscripten only sse2 and sse4.1 are tested (NEON will succeed in
being enabled, but fail to build). This is consistent with
the current behavior added in:

WASM-SIMD: port 2 patches from rreverser@'s tree
* Stop on first found SIMD version
* Imply lower SSE version when higher is found
Bug: webp:488
Change-Id: I34d01274e5204a477b6b9f35ed566048a62b4c57
Tested: msvc 2013-2019 debug win32/x64 builds; clang-cl under 2019
- Add `-msimd128` to flags to actually enable WebAssembly SIMD
when performing SIMD detection. It's currently required in
addition to `-msse*` / `-mfpu=neon` flags which only perform
translation of corresponding intrinsics to Wasm SIMD ones.
See a discussion at emscripten-core/emscripten#12714 for
automating this and making easier in the future.
- Remove compilation branch that prevented definitions of
`WEBP_USE_SSE` and `WEBP_USE_NEON` on Emscripten even when
SIMD support was detected at compile-time.
- Add an implementation of `VP8GetCPUInfo` for Emscripten which
uses static `WEBP_USE_*` flags to determine if a corresponding
SIMD instruction is supported. This is because Wasm doesn't
have proper feature detection (yet) and requires making separate
build for SIMD version anyway.

so add a space after the first one to keep it.

- some image libraries define _INCLUDE_DIR and not INCLUDE_DIRS.
- CMakePushCheckState is a non-destructive way of changing the
CMAKE_REQUIRED_* variables.

GIF find_package only locates the header and library, it doesn't fail
compile tests when detecting the version, but falls back to 3 (as of at
least cmake 3.7.2). Make sure the library links to avoid incorrect
detection when cross compiling.

this avoids the result being cached in a common variable causing
potentially incorrect results in future tests and improves the logging

This is duplicating code from compiler flag checking that was once
added (then reverted to CMake) as the problem seem to be on the
clang side as detailed in:
http://public.kitware.com/Bug/view.php?id=13194
I also tried to remove a similar warning with pthreads but there
is also an issue on the clang side:

This will well isolate contributions for original code,

The goal is not to replace our autotools configuration, but to
provide a minimal CMake file that can build the lib, cwebp and
dwebp.
