I am trying to recompile ImageMagick to enable webp support for PHP.
The issue appears to be that when compiling Imagick using ./configure --with-webp=yes it cannot find a libwebp library with a higher version than 0.4.1. Amazon Linux 2's repos only go up to version 0.3.1. This means compiling libwebp from source, which works but Imagick does not seem to recognize it.
So my question is, how do I ensure ImageMagick can find and use the libwebp library?
Steps
To compile from the source I have done the following:
cd /var
sudo wget https://storage.googleapis.com/downloads.webmproject.org/releases/webp/libwebp-1.1.0.tar.gz
sudo tar xvzf libwebp-1.1.0.tar.gz
cd libwebp-1.1.0
sudo ./configure
sudo make && sudo make install
/sbin/ldconfig -p | grep webp shows the following output which shows libwebp library exists in the /usr/local/lib dir as expected and registered in the ld config.
libwebpdemux.so.2 (libc6,x86-64) => /usr/local/lib/libwebpdemux.so.2
libwebpdemux.so (libc6,x86-64) => /usr/local/lib/libwebpdemux.so
libwebp.so.7 (libc6,x86-64) => /usr/local/lib/libwebp.so.7
libwebp.so (libc6,x86-64) => /usr/local/lib/libwebp.so
I then try to compile Imagick from source by doing the following:
cd /var
sudo wget https://imagemagick.org/download/ImageMagick.tar.gz
sudo tar xvzf ImageMagick.tar.gz
cd ImageMagick-7.1.0-7
sudo ./configure --with-webp=yes
sudo make && sudo make install
sudo ldconfig /usr/local/lib
However, when running ./configure --with-webp=yes, I get the following output
...
