Changes:

• CMake: fix typo in CMAKE_INSTALL_BINDIR install target that affects location of geotiff.dll (#117)

Changes:

• GTIFGetDatumInfoEx(): handle dynamic datums
• CMake: adopt GNUInstallDirs
• CMake: export TIFF as a public dependency
• Add XTIFFClientOpenExt() with re-entrant error callbacks
• listgeo: add a -no_corners option to avoid printing corner
  coordinates which might be PROJ version sensitive (refs #81)
• Fix test failures with PROJ 9.1.1 and 9.3
• Remove trailing spaces from many files.
• Localize variables and add const when possible in a number of files
• geo_normalize.c: sprintf --> snprintf
• Add missing includes
• Fix -Werror=calloc-transposed-args with gcc 14
• FindPROJ.cmake: proj_experimental;h -> proj_experimental.h
• CMake: add a BUILD_SHARED_LIBS option, and make it default to ON
• autoconf/CMake: add generation of libgeotiff.pc
• Remove INSTALL and install-sh autoconf-generated files

Changes:

• geotiff.h: more precise signature for GTIFDirectoryInfo()
• applygeo.c/geotifcp.c: use uint16/32_t instead of old libtiff non _t custom types
• Bump CMake min to 3.0.0 and remove apparently unneeded cmake_policy() declarations
• CMake: remove libjpeg and libz from linking of libgeotiff itself.
• geo_config.h: prefix HAVE_xxx and restrict it to GEOTIFF_HAVE_STRINGS_H (fixes #61)
• GTIFPrintDefn(): avoid potential nullptr deref. CID 1469240
• CMake: use variable for installation subdirectories, and make sure INTERFACE_INCLUDE_DIRECTORIES is exported (fixes #67)
• ReadKey(): only allow reading a key with TIFFTagLocation=0 that has a count of 1 to avoid reading an illegal address (and crashing) when using GTIFKeyGet() or PrintKey() (fixes #66)
• ReadKey(): add extra warning messages
• CMake: avoid INTERFACE_LINK_LIBRARIES vs LINK_INTERFACE_LIBRARIES_DEBUG warning about TIFF
• CMake: Fix dllexport
• CMake: Revise exported cmake config wrt BUILD_SHARED_LIBS
• CMake: Revise exported cmake config wrt dependencies
• CMake: Respect _FIND_QUIETLY

Changes:

• Add CoordinateEpochGeoKey = 5120 of type DOUBLE to store coordinate epoch of tie points / geotransform matrix for dynamic CRS.
  See opengeospatial/geotiff#99
• geo_normalize.h/c: rename variables to please codespell
• GTIFGetGCSInfoEx(): use proj_crs_get_datum_forced() for PROJ >= 8 to avoid issues with datum ensembles (fixes #54)
• GTIFGetGCSInfoEx(): remove dead code (GDAL Coverity CID 1432690)
• geo_normalize.c: follow-up to e06625c to avoid look up of user-defined GeogGeodeticDatumGeoKey that cause PROJ warnings (fixes #41)

New features:

• Add support for OGC GeoTIFF 1.1
• Expose GTIFGetPCSInfoEx(), GTIFGetProjTRFInfoEx(), GTIFGetGCSInfoEx(), GTIFGetDatumInfoEx(), GTIFGetEllipsoidInfoEx(), GTIFGetPMInfoEx(), GTIFGetUOMLengthInfoEx() and GTIFGetUOMAngleInfoEx() so that users can specify their own PROJ context
• Add GTIFKeyGetASCII(), GTIFKeyGetSHORT() and GTIFKeyGetDOUBLE() as safer variants of
  GTIFKeyGet() with type checking
• autotools build: enable build in a separate tree from source (#37) (fixes #28)
• Use pkg-config for libtiff detection

Bug fixes:

• GTIFDecToDMS(): fix rounding issue (refs #16)
• geo_names.c: Silence warning in GetNameFromDatabase
• cpl_serv.h: add parenthesis in macro definitions
• Fix spelling errors
• geo_normalize.c: set UOMLength from GeogLinearUnits (for geocentic CRS) (GDAL #1595)
• testlistgeo: remove hardcoded path in test output (fixes #16 (comment))
• Adapt test script for PROJ 6.2 EPSG database (fixes #22)
• Use unix EOL for cmake related files (fixes #14)
• configure.ac: drop dead code
• geo_normalize.c: avoid look up of user-defined geokeys that cause PROJ warnings (fixes GDAL #2321)
• listgeo: fix corner coordinates for images with RasterPixelIsPoint (#36)
