Windows Build

[Vitch612]

Compiling on windows does not work when done using the lz4 library source code. This can probably be fixed by producing the proper nmake makefiles for it. A quicker workaround is to compile the liblz4 visual studio project, take the produced library liblz4_static.lib rename it to liblz4.lib and put it in the folder:
<php source root>\no\lib\
Also copy the header files lz4.h and lz4hc.h to the folder
<php source root>\no\include\
If the desired outcome is an extension dll edit config.w32 in the lz4 extension folder and replace the EXTENSION lines with:
EXTENSION("lz4", "lz4.c", true, "/DZEND_ENABLE_STATIC_TSRMLS_CACHE=1");
This last step is only necessary if someone like myself does not know how to get the PHP_LZ4_SHARED variable to have true as a value and a dll is preferred to a monolitic php build.
