By running:
nmake /f Makefile.vc CFG=release-static RTLIBCFG=static OBJDIR=output
the directory output\release-static\(x64|x86)\bin will contain the tools cwebp.exe and dwebp.exe. The directory output\release-static\(x64|x86)\lib will contain the libwebp static library. The target architecture (x86/x64) is detected by Makefile.vc from the Visual Studio compiler (cl.exe) available in the system path.
On platforms with GNU tools installed (gcc and make), running
make -f makefile.unix
will build the binaries examples/cwebp and examples/dwebp, along with the static library src/libwebp.a. No system-wide installation is supplied, as this is a simple alternative to the full installation system based on the autoconf tools (see below). Please refer to makefile.unix for additional details and customizations.
Prerequisites: a compiler (e.g., gcc), make, autoconf, automake, libtool.
On a Debian-like system the following should install everything you need for a minimal build:
$ sudo apt-get install gcc make autoconf automake libtool
When building from git sources, you will need to run autogen.sh to generate the configure script.
./configure make make install
should be all you need to have the following files
/usr/local/include/webp/decode.h /usr/local/include/webp/encode.h /usr/local/include/webp/types.h /usr/local/lib/libwebp.* /usr/local/bin/cwebp /usr/local/bin/dwebp
installed.
Note: A decode-only library, libwebpdecoder, is available using the --enable-libwebpdecoder flag. The encode library is built separately and can be installed independently using a minor modification in the corresponding Makefile.am configure files (see comments there). See ./configure --help for more options.

You can download and install libwebp using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install ./vcpkg install libwebp
The libwebp port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
With CMake, you can compile libwebp, cwebp, dwebp, gif2webp, img2webp, webpinfo and the JS bindings.
Prerequisites: a compiler (e.g., gcc with autotools) and CMake.
On a Debian-like system the following should install everything you need for a minimal build:
$ sudo apt-get install build-essential cmake
When building from git sources, you will need to run cmake to generate the makefiles.
mkdir build && cd build && cmake ../ make make install
If you also want any of the executables, you will need to enable them through CMake, e.g.:
cmake -DWEBP_BUILD_CWEBP=ON -DWEBP_BUILD_DWEBP=ON ../
or through your favorite interface (like ccmake or cmake-qt-gui).
Use option -DWEBP_UNICODE=ON for Unicode support on Windows (with chcp 65001).
Finally, once installed, you can also use WebP in your CMake project by doing:
find_package(WebP)
which will define the CMake variables WebP_INCLUDE_DIRS and WebP_LIBRARIES.
The support for Gradle is minimal: it only helps you compile libwebp, cwebp and dwebp and webpmux_example.
Prerequisites: a compiler (e.g., gcc with autotools) and gradle.
On a Debian-like system the following should install everything you need for a minimal build:
$ sudo apt-get install build-essential gradle
When building from git sources, you will need to run the Gradle wrapper with the appropriate target, e.g. :
./gradlew buildAllExecutables
To generate language bindings from swig/libwebp.swig at least swig-1.3 (http://www.swig.org) is required.
Currently the following functions are mapped:
Decode:
WebPGetDecoderVersion WebPGetInfo WebPDecodeRGBA WebPDecodeARGB WebPDecodeBGRA WebPDecodeBGR WebPDecodeRGB
Encode:
WebPGetEncoderVersion WebPEncodeRGBA WebPEncodeBGRA WebPEncodeRGB WebPEncodeBGR WebPEncodeLosslessRGBA WebPEncodeLosslessBGRA WebPEncodeLosslessRGB WebPEncodeLosslessBGR
See also the swig documentation for more detailed build instructions and usage examples.
To build the swig-generated JNI wrapper code at least JDK-1.5 (or equivalent) is necessary for enum support. The output is intended to be a shared object / DLL that can be loaded via System.loadLibrary("webp_jni").
To build the swig-generated Python extension code at least Python 2.6 is required. Python < 2.6 may build with some minor changes to libwebp.swig or the generated code, but is untested.
Libwebp can be compiled into a JavaScript decoder using Emscripten and CMake. See the corresponding documentation
