Integration with CMake build systems
GTK-Doc now provides a GtkDocConfig.cmake module (and the corresponding GtkDocConfigVersion.cmake module). This provides a gtk_doc_add_module command that you can set in your CMakeLists.txt file.
The following example shows how to use this command.
Example 2-8 Example of using GTK-Doc from CMake
find_package(GtkDoc 1.25 REQUIRED)
# Create the doc-libmeep target.
gtk_doc_add_module(
libmeep ${CMAKE_SOURCE_DIR}/libmeep
XML meep-docs.xml
LIBRARIES libmeep
)
# Build doc-libmeep as part of the default target. Without this, you would
# have to explicitly run something like `make doc-libmeep` to build the docs.
add_custom_target(documentation ALL DEPENDS doc-libmeep)
# Install the docs. (This assumes you're using the GNUInstallDirs CMake module
# to set the CMAKE_INSTALL_DOCDIR variable correctly).
install(DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/libmeep/html
DESTINATION ${CMAKE_INSTALL_DOCDIR})
