I was trying to build flann from source in Windows-10 using cmake. During the installation process it says it cannot find liblz4. I tried two method :
1) So I downloaded the prebuild lz4 from here (https://github.com/lz4/lz4/releases) and placed the C:\XXXX\Downloads\lz4_v1_9_1_win64\dll to my env path.
2) I used vcpkg to install lz4 first. Then did
C:\source\flann\build> cmake .. -DCMAKE_TOOLCHAIN_FILE=C:\XXXXXX\source\vcpkg\scripts\buildsystems\vcpkg.cmake -G "Visual Studio 15 2017 Win64"
.
None of the above two method worked. I still get cannot find liblz4 error.
