I am using CMake 2.8 on Linux and Windows.
When I include() or find_package() a .cmake file, is there a variable that I
can use within the included .cmake file that will tell me its path?
For example,
# In CMakeLists.txt
include(somePath/foo.cmake)
Within somePath/foo.cmake, I want to include bar.cmake which is in the same
directory as foo.cmake,
# In somePath/foo.cmake
include(${CMAKE_VARIABLE_THAT_IS_THE_ANSWER_TO_THIS_QUESTION}/bar.cmake)
where ${CMAKE_VARIABLE_THAT_IS_THE_ANSWER_TO_THIS_QUESTION} = "somePath", the
path to foo.cmake, which is currently being evaluated.
