Zitat von Raymond Wan <r....@aist.go.jp>:
Hi all,I'm having a problem which I can't quite figure out how to solve. Basically, I have C++ source code in two directories, each for a different class. Let's say: src/X src/Y Each one makes a different class but ultimately X makes use of Y (i.e., an instance of Y is a variable within X's definition). Separating them allows me to test Y independently. So, Y uses CMake to locate the zlib library and whether or not it is found is passed to Y's source code via a configuration file. i.e., I have: #cmakedefine ZLIB_FOUND 1 in the configuration file which is created like this in CMakeLists.txt: CONFIGURE_FILE ( "${PROJECT_SOURCE_DIR}/Config.hpp.in" "${PROJECT_BINARY_DIR}/Config.hpp" ) INCLUDE_DIRECTORIES ("${PROJECT_BINARY_DIR}") I think/hope so far things are ok... I can compile Y and run it with no problems. The problem is that X needs access to this generated configuration file, too. At the very least, it needs to know the size of an instance of Y in order to allocate memory for it.
Did you consider alternatives like giving Y a static function that returns a new instance of Y? That makes your problem void. If this is all within a project that is not going to be separated later, just put the common configuration into the parent directory of both
