+Subject: [PATCH] Use absolute CMAKE_INSTALL_FULL_LIBDIR for libdir in
+ pkgconfig files
+
+According to cmake GNUInstallDirs documentation, CMAKE_INSTALL_LIBDIR
+may be either absolute or relative to CMAKE_INSTALL_PREFIX. Use
+CMAKE_INSTALL_FULL_LIBDIR, which is always the full absolute path.
+
+Remove unused exec_prefix variable.
+
+Fixes https://github.com/AcademySoftwareFoundation/openexr/issues/595
