Wan-Teh Chang ffa8efbb11 Set IMPORT_PREFIX to "lib" on Windows 
Fix the follwing Ninja warning:
ninja: warning: multiple rules generate yuv.lib. builds involving this
target will not be correct; continuing anyway [-w dupbuild=warn]

Without this change, both the static library and the DLL's import
library are named "yuv.lib". With this change, the DLL's import library
is named "libyuv.lib", corresponding to the DLL name "libyuv.dll".

README.md

libyuv is an open source project that includes YUV scaling and conversion functionality.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats for compression.
  • Convert to RGB formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSSE3/AVX2 on x86/x64.
  • Optimized for Neon on Arm.
  • Optimized for MSA on Mips.
