Lensfun provides lens distoration correction for Darktable and other raw processing applications. Version 0.3.95 provides ability to use the
Adobe Camera Model, and hence use Adobe lens profiles (lcp files). However, lensfun 0.3.95 is not packaged for Debian Buster. Also Darktable won’t compile against the latest git version of Lensfun, so you must compile and install specifically version 0.3.95 to get ACM support.
We begin by downloading and extracting Lensfun 0.3.95. Lensfun 0.3.95 is not tagged in git, so we have to download the release directly from SourceForge. The release is not available from the GitHub repository.
$ wget https://sourceforge.net/projects/lensfun/files/0.3.95/lensfun-0.3.95.tar.gz
$ tar -xvf lensfun-0.3.95.tar.gz
$ cd lensfun-0.3.95/
Lensfun uses CMake for building and has also has CPack enabled. We can use it to build a deb package and install it. This allows easier integration and uninstallation in the future.
$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=release -DCPACK_BINARY_DEB=ON ../
$ make -j`nproc` && make package
$ sudo apt install ./liblensfun2_0.3.95.0_amd64.deb
