catkin share directory vs. workspace directory [closed]

asked 2015-05-05 13:16:16 -0500


How can I set a variable inside my CMakeLists.txt to set a variable to point to a file into the workspace which also points to the same file but in the share directory when installed.


I want to install a "foo.c" inside my_package/src/. Now when installed, it should be in the same directory as the files in the package but in the share folder, so that other later workspaces can compile the source file into there code with a macro this way:

add_executable(foo_node ... ${MY_PACKAGE_SOURCE})

You package can use a custom CFG_EXTRAS file to set arbitrary variables when your package is being found:

An example package which sets variable to different location in devel-space and in install-space would be:

I added it but now it tells me the following on compilation: Parse error. Expected a command name, got unquoted argument with text "@[if".

If I comment out the if and else statements, it works but the @CMAKE_CURRENT_SOURCE_DIR is not translated into a path when I use message() to print it inside the cmake file: Output is like @(CMAKE_CURRENT_SOURCE_DIR)/src/ is that normal?

You either gave the filename the wrong extension or have a syntax error in the empy template.
