I have some third party non-CMake-configured source packages I want to include in my CMake project and apply a CMake 'wrapper' to.
So, for example, in case of software package 'foo', I would like to unpack the original foo-src/foo.tar.gz archive into directory foo/, copy my own custom foo-src/CMakeLists.txt into foo/ as well, and then process foo/ itself further with CMake using add_subdirectory(foo). Unfortunately, the add_subdirectory(foo) statement always causes CMake to complain that directory 'foo' does not exist, even though I have created a working custom_target for 'foo' that will actually create it. (I know, I know -- it was naive of me to expect that the argument to add_subdirectory() would be itself interpreted as a target.) Is there any way to have CMake create a directory, and *then* process that directory as a subdirectory, in a single pass? I can do the unpacking unconditionally in an 'execute_process()' call, but one of the goals of the exercise is to have CMake use dependency information and *only* unpack foo.tar.gz if (a) either foo/ does not exist yet, or (b) foo.tar.gz itself or the custom CMakeLists.txt file have changed. Does anybody here have any suggestions for me? -- Leo Breebaart <[EMAIL PROTECTED]> _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
