# actual install

This works great with the below tweaks for ImageMagick-6.9.10.68-3 which also required an extra thing not previously listed "lcms2-devel"

yum -y install bzip2-devel libtiff-devel giflib-devel ghostscript-devel libwmf-devel jasper-devel libtool-ltdl-devel libXext-devel libXt-devel librsvg2-devel OpenEXR-devel libwebp-devel lcms2-devel
rpm -ivh http://vault.centos.org/7.8.2003/os/Source/SPackages/ImageMagick-6.9.10.68-3.el7.src.rpm
sed -i '/BuildRequires:\tghostscript-devel/a BuildRequires:\tlibwebp-devel' /root/rpmbuild/SPECS/ImageMagick.spec
sed -i '/Requires: pkgconfig/a Requires: libwebp' /root/rpmbuild/SPECS/ImageMagick.spec
rpm -Uvh --force /root/rpmbuild/RPMS/x86_64/ImageMagick-6.9.10.68-3.el7.x86_64.rpm

Check for it:
identify -list format| grep webp

root@server [/root/]# identify -list format| grep webp
     WEBP* WEBP      rw-   WebP Image Format (libwebp 0.3.0 [0201])

Cant figure it out. Gives that error.. centos 7 ec2 machine w/plesk

Try:
yum remove ImageMagick

Then
rpm -Uvh --force /root/rpmbuild/RPMS/x86_64/ImageMagick-6.9.10.68-3.el7.x86_64.rpm
