# This is FindGTSAM.cmake

|
|
# DEPRECIATED: Use config file approach to pull in targets from gtsam
|
||
|
|
# CMake module to locate the GTSAM package
|
||
|
|
#
|
||
|
|
# The following cache variables may be set before calling this script:
|
||
|
|
#
|
||
|
|
# GTSAM_DIR (or GTSAM_ROOT): (Optional) The install prefix OR source tree of gtsam (e.g. /usr/local or src/gtsam)
|
||
|
|
# GTSAM_BUILD_NAME: (Optional) If compiling against a source tree, the name of the build directory
|
||
|
|
# within it (e.g build-debug). Without this defined, this script tries to
|
||
|
|
# intelligently find the build directory based on the project's build directory name
|
||
|
|
# or based on the build type (Debug/Release/etc).
|
||
|
|
#
|
||
|
|
# The following variables will be defined:
|
||
|
|
#
|
||
|
|
# GTSAM_FOUND : TRUE if the package has been successfully found
|
||
|
|
# GTSAM_INCLUDE_DIR : paths to GTSAM's INCLUDE directories
|
||
|
|
# GTSAM_LIBS : paths to GTSAM's libraries
|
||
|
|
#
|
||
|
|
# NOTES on compiling against an uninstalled GTSAM build tree:
|
||
|
|
# - A GTSAM source tree will be automatically searched for in the directory
|
||
|
|
# 'gtsam' next to your project directory, after searching
|
||
|
|
# CMAKE_INSTALL_PREFIX and $HOME, but before searching /usr/local and /usr.
|
||
|
|
# - The build directory will be searched first with the same name as your
|
||
|
|
# project's build directory, e.g. if you build from 'MyProject/build-optimized',
|
||
|
|
# 'gtsam/build-optimized' will be searched first. Next, a build directory for
|
||
|
|
# your project's build type, e.g. if CMAKE_BUILD_TYPE in your project is
|
||
|
|
# 'Release', then 'gtsam/build-release' will be searched next. Finally, plain
|
||
|
|
# 'gtsam/build' will be searched.
|
||
|
|
# - You can control the gtsam build directory name directly by defining the CMake
|
||
|
|
# cache variable 'GTSAM_BUILD_NAME', then only 'gtsam/${GTSAM_BUILD_NAME} will
|
||
|
|
# be searched.
|
||
|
|
# - Use the standard CMAKE_PREFIX_PATH, or GTSAM_DIR, to find a specific gtsam
|
||
|
|
# directory.
|
||
|
|
|

|
