Installation of Exiv2

Prepare Exiv2 by running the following commands: 

cmake -B build -G Ninja              \
      -D CMAKE_INSTALL_PREFIX=/usr   \
      -D CMAKE_BUILD_TYPE=Release    \
      -D EXIV2_ENABLE_VIDEO=yes      \
      -D EXIV2_ENABLE_WEBREADY=yes   \
      -D EXIV2_ENABLE_CURL=yes       \
      -D EXIV2_BUILD_SAMPLES=no      \
      -D CMAKE_SKIP_INSTALL_RPATH=ON
ninja -C build

To test the results, issue: 

ninja -C build test

Now Install the package, as the root user: 

ninja -C build install

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-62.

-D EXIV2_ENABLE_BROTLI=no: Use this switch if you have not installed Brotli-1.2.0.
