v5.2 didn't build with CMake. Other branches had
include(CMakePushCheckState) in top-level CMakeLists.txt
which made the build work.
Fixes: 597f49b614
(cherry picked from commit be4bf94446)
A CMake option LARGE_FILE_SUPPORT is created if and only if
-D_FILE_OFFSET_BITS=64 affects sizeof(off_t).
This is needed on many 32-bit platforms and even with 64-bit builds
with MinGW-w64 to get support for files larger than 2 GiB.
