Using GDAL in CMake projects
Added in version 3.5.
The recommended way to use the GDAL library 3.5 or higher in a CMake project is to
link to the imported library target GDAL::GDAL
provided by
the CMake configuration which comes with the library. Typical usage is:
find_package(GDAL CONFIG REQUIRED)
target_link_libraries(MyApp PRIVATE GDAL::GDAL)
By adding the imported library target GDAL::GDAL
to the
target link libraries, CMake will also pass the include directories to
the compiler.
The CMake command find_package
will look for the configuration in a
number of places. The lookup can be adjusted for all packages by setting
the cache variable or environment variable CMAKE_PREFIX_PATH
. In
particular, CMake will consult (and set) the cache variable
GDAL_DIR
.
Before GDAL 3.5, it is recommended to use find module supplied with CMake.
This also creates the GDAL::GDAL
target. It requires CMake version 3.14.
cmake_minimum_required(VERSION 3.14)
find_package(GDAL CONFIG)
if(NOT GDAL_FOUND)
find_package(GDAL REQUIRED)
endif()
target_link_libraries(MyApp PRIVATE GDAL::GDAL)
