Command Explanations

-D CMAKE_SKIP_INSTALL_RPATH=ON: This switch makes cmake remove hardcoded library search paths (rpath) when installing a binary executable file or a shared library. This package does not need rpath once it's installed into the standard location, and rpath may sometimes cause unwanted effects or even security issues.

-D EXIV2_ENABLE_VIDEO=yes: This switch enables managing video metadata.

-D EXIV2_ENABLE_WEBREADY=yes: This switch enables managing web image metadata.

-D EXIV2_BUILD_SAMPLES=no: This switch is necessary to suppress building and installing sample programs. If the sample programs are built, 34 additional programs are installed in /usr/bin.

-D EXIV2_ENABLE_CURL=yes: This switch is necessary to enable network/http capabilities.

-D EXIV2_ENABLE_INIH=no: Use this switch if you have not installed inih-58.

-D EXIV2_ENABLE_BROTLI=no: Use this switch if you have not installed Brotli-1.1.0.
