Subject: [PATCH] Add Findoctomap module
|
||||
|
||||
octomap's authors use absolute paths in the cmake module they
|
||||
ship together with the package. This makes the module unusable
|
||||
in cross-compilation environments or requires additional
|
||||
tweaking (e.g. see https://github.com/bmwcarit/meta-ros/blob/43bd17e8839f4078351895eca361804f19efb13c/recipes-ros/octomap-ros/octomap-ros_0.4.0.bb#L16)
|
||||
|
||||
This patch overrides the module in order to ease octomap's
|
||||
usage in cross-compilation environments.
|
||||

||||

+# Input variables:
|

+#
|
||||
+# - Octomap_ROOT_DIR (optional): When specified, header files and libraries will be searched for in
|
||||
+# ${Octomap_ROOT_DIR}/include
|
||||
+# ${Octomap_ROOT_DIR}/libs
|
||||
+# respectively, and the default CMake search order will be ignored. When unspecified, the default
|
||||
+# CMake search order is used.
|
||||
+# This variable can be specified either as a CMake or environment variable. If both are set,
|
||||
+# preference is given to the CMake variable.
|
||||
+# Use this variable for finding packages installed in a nonstandard location, or for enforcing

||||
+# - Otomap_INCLUDE_DIRS: Paths to the necessary header files
|
||||
+# - Octomap_LIBRARIES: Package libraries
|
||||
+#
|
