f892f82883 Suppress false positive warning from MSVC (datagencli.c) 
MSVC 2022 reports the follwing false positve warnings:

lz4\tests\datagencli.c(110): warning C26451: Arithmetic overflow: Using operator '-' on a 4 byte value and then casting the result to a 8 byte value. Cast the value to the wider type before calling operator '-' to avoid overflow (io.2).
lz4\tests\datagencli.c(134): warning C26451: Arithmetic overflow: Using operator '-' on a 4 byte value and then casting the result to a 8 byte value. Cast the value to the wider type before calling operator '-' to avoid overflow (io.2).
lz4\tests\datagencli.c(146): warning C26451: Arithmetic overflow: Using operator '-' on a 4 byte value and then casting the result to a 8 byte value. Cast the value to the wider type before calling operator '-' to avoid overflow (io.2).

Although they're absolutely compiler's and static analyzer's bug,
it'd always be nice to use the standard library.

af0d7c0cb8 Suppress warning from rc.exe 
Since rc.exe (the resource compiler) is legacy compiler,  it truncates preprocessor symbol name length to 32 chars.
And it reports the following warning

lz4\build\VS2022\..\..\lib\lz4.h(314): warning RC4011: identifier truncated to 'LZ4_STATIC_LINKING_ONLY_DISABLE'
lz4\build\VS2022\..\..\lib\lz4.h(401): warning RC4011: identifier truncated to 'LZ4_STATIC_LINKING_ONLY_DISABLE'

This patch detects rc.exe and just skips long symbol.

0fc36f1bc7 Suppress false positive warning from MSVC 
MSVC (17.3 or earlier) reports the following warning

lz4\lib\lz4.c(527): warning C6385: Reading invalid data from 'v'.
Line 527 is : LZ4_memcpy(&v[4], v, 4);

But, obviously v[0..3] is always filled with meaningful value.
Therefore, this warning report is wrong.

We must revisit this issue with future version of MSVC.

ec487d3265 faster CLI decompression speed for frames with -BD4 setting 
lz4frame favors the faster prefix mode
when decompressing a frame with linked blocks.

This significantly improved CLI decompression on files compressed with -BD4 setting.
On my laptop, decompressing `enwik9` went from 0.89s to 0.52s.

This improvement is only for linked blocks.
It's more visible for small block sizes.

a28421e129 cmake: move cmake_minimum_required() before project() 
cmake_minimum_required() must always be the first instruction of a CMakeLists.
project() should come after cmake_minimum_required() as soon as possible. Therefore option() are moved after project().
