FindFLTK¶
Finds the Fast Light Toolkit (FLTK), a cross-platform toolkit for GUI development.
FLTK uses CMake-based build system and provides a package configuration file for
projects to find it. As of its 1.4.0 version it also provides
Imported Targets that encapsulate usage requirements. For example,
fltk::fltk
, which can be linked to project targets where FLTK is needed.
This module takes that into account and first attempts to find FLTK in
config mode. If the configuration file is not available, it falls back to
module mode and searches standard locations. See also to the official FLTK
documentation for more information, how to use FLTK with CMake.
在 3.11 版被加入: Debug and Release library variants are found separately and use per-configuration variables.
結果變數¶
This module defines the following variables:
FLTK_FOUND
Boolean indicating whether FLTK is found.
FLTK_LIBRARIES
Libraries needed to link against to use FLTK.
FLTK_WRAP_UI
Boolean indicating whether the
fluid
executable is found. This variable is available only if FLTK is found in module mode and can be used, for example, to conditionally invoke thefltk_wrap_ui()
command if it is needed and available.
快取變數¶
The following cache variables are also available to set or use:
FLTK_FLUID_EXECUTABLE
The path to the
fluid
binary tool.FLTK_INCLUDE_DIR
The include directory containing header files needed to use FLTK.
FLTK_BASE_LIBRARY_RELEASE
在 3.11 版被加入.
The path to the release (optimized) FLTK base library.
FLTK_BASE_LIBRARY_DEBUG
在 3.11 版被加入.
The path to the debug FLTK base library.
FLTK_GL_LIBRARY_RELEASE
在 3.11 版被加入.
The path to the release (optimized) FLTK GL library.
FLTK_GL_LIBRARY_DEBUG
在 3.11 版被加入.
The path to the debug FLTK GL library.
FLTK_FORMS_LIBRARY_RELEASE
在 3.11 版被加入.
The path to the release (optimized) FLTK Forms library.
FLTK_FORMS_LIBRARY_DEBUG
在 3.11 版被加入.
The path to the debug FLTK Forms library.
FLTK_IMAGES_LIBRARY_RELEASE
在 3.11 版被加入.
The path to the release (optimized) FLTK Images protobuf library.
FLTK_IMAGES_LIBRARY_DEBUG
在 3.11 版被加入.
The path to the debug FLTK Images library.
輸入變數¶
By default, this module searches for all FLTK libraries and its fluid
executable. The following variables can be set before calling
find_package(FLTK)
to indicate which elements are optional for a successful
configuration:
FLTK_SKIP_FLUID
Set to boolean true to mark the
fluid
executable as optional.FLTK_SKIP_FORMS
Set to boolean true to mark the FLTK Forms library as optional; it will therefore not be included in the
FLTK_LIBRARIES
result variable.FLTK_SKIP_IMAGES
Set to boolean true to mark the FLTK Image library as optional; it will therefore not be included in the
FLTK_LIBRARIES
result variable.FLTK_SKIP_OPENGL
Set to boolean true to mark the FLTK OpenGL library as optional; it will therefore not be included in the
FLTK_LIBRARIES
result variable.
範例¶
Finding FLTK and conditionally creating a fltk::fltk
imported interface
target, if it is not provided by the upstream FLTK package. Imported target can
then be linked to a project target:
find_package(FLTK)
if(FLTK_FOUND AND NOT TARGET fltk::fltk)
add_library(fltk::fltk INTERFACE IMPORTED)
set_target_properties(
fltk::fltk
PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES "${FLTK_INCLUDE_DIR}"
INTERFACE_LINK_LIBRARIES "${FLTK_LIBRARIES}"
)
endif()
target_link_libraries(project_target PRIVATE fltk::fltk)
